The scope of this standard covers the design and installation of low voltage reticulation systems

including, sources of supply, cables (types, selection, segregation, routing, wiring method etc.), cable

enclosures and support systems, switchboards, circuit protection, voltage drops and fault operation.

National standards, international standards and national legislation shall take precedence over this

standard where they present a higher level of service or protection.

2.1 Mandatory and Non-Mandatory Requirements

The following language key describes the requirements of imperative statements within this Standard.

The word:

Shall - describes mandatory requirements;

Should - describes non-mandatory best practice recommendations; and

May - describes possible options that are not mandatory or best practice.

2.2 Limits of Standard

Users of this Standard shall explicitly demonstrate compliance with this Standard. Compliance shall

be demonstrated through:

Adopting appropriate standards and providing explicit reasons for their selection; or

Providing an explicit, evidence based, business case supporting compliance with this standard.

The general statement “in accordance with Melbourne Airport Standards”, shall not be deemed

acceptable without further detail.

TECHNICAL STANDARD


4 DEFINITIONS

4.1 Terms and Definitions

Acronym Definition

Aero Refers to the Airport itself as opposed to the Business park and surrounds.

Airside Areas of Melbourne Airport, including the airfield, apron and parts of the terminal buildings to which access is controlled.

Circuit breaker A switch that automatically interrupts the flow of electric current if the current exceeds a pre-set limit, measured in amperes. Circuit breakers are used most often as a safety precaution where excessive current through a circuit could be experienced. However, it is utilised to protect the electrical infrastructure. Unlike fuses, they can usually be reset and re-used.

Consumer’s mains These are the conductors between the point of attachment and the service equipment. They are determined in accordance with the Victorian Service and Installation Rules and AS/NZS 3000.

Contractor

The term Contractor, in the context of this standard, means either a building or electrical contractor responsible for and licensed by Energy Safe Victoria, to undertake electrical work referred to herein.

Criticality A measure of the Service Level that an electrical system is designed to provide. In levels of descending criticality: Aero Critical; Aero Essential; Aero Non-Essential.

Critical An electrical load that is required to:

Stay ON through short duration mains outages

Stay ON through Medium duration mains outages

Stay ON through Long duration mains outages

Stay ON through Extended mains outages

Designer A competent skilled person to undertake design work on an APAM project. Designers may be APAM employees, contractors, consultants or employed by consultants.

Discrimination Electrical discrimination is achieved when a lower rated protective device (circuit breaker or fuse) located closer to an electrical fault, operates before a higher rated circuit breaker which is further away (upstream) from the lower rated device and the fault. Without discrimination, if an upstream protective device operated before or at the same time as the downstream device, then circuits that do not have a fault would also trip.

Distribution board (DB) This is a switchboard that is downstream from a major switchboard, such as the Installation Supply Main Switchboard. Its purpose is to be located in a targeted electrical load area thus reducing the required cable sizes and to better deal with volt drop issues.

Essential An electrical load that shall:


TECHNICAL STANDARD


Acronym Definition

Experience a mains outage through short duration mains outages

Stay ON through Medium duration mains outages

Stay ON through Long duration mains outages


Earthing system This includes the earth grid and all conductors, piping, electrodes, clamps and other metalwork connected thereto. Whereas the Local Electricity Distributors generally use a Multiple Earthed Neutral (MEN) earthing system.

Electrical fixture A power outlet, light fitting (or group of fittings), permanently connected electrical equipment that is supplied by an electrical circuit for its operation or for the operation of devices connected thereto.

Electrolysis Refers to the process where corrosion occurs to a buried metal structure when DC current leaves the structure to enter the electrolyte of the surrounding soil. The degree and rapidity of electrolytic action depends upon the amount of current flowing, and the type of soluble salts found in the surrounding soil. Chlorides or nitrates in a clayey or loamy soil favour electrolytic action, whereas minimum electrolytic corrosion occurs in clean, dry sand.

High voltage (HV) this is a voltage exceeding 1000 Vac or 1500 Vdc.

IP rating This is the Ingress Protection rating which denotes the environmental protection provided by enclosures e.g. switchboard panels. The IP rating normally has two numbers (refer to AS 60529):

the first digit represents protection against ingress of solid objects

the second digit represents protection against ingress of liquids

Life-cycle costing A procurement costing technique that considers all life cycle costs. The aim is to determine the lowest cost of ownership of a fixed asset (initial price, installation, operation, maintenance, upgrading, disposal, and other costs) during the asset's economic life.

Like for like replacement This is a change in an installation element, usually considered to be minimal in nature, not requiring confirmatory validation testing e.g. replacing an existing water heater with one of similar rating but which may differ in appearance and manufacturer. In all situations safety must not be compromised.

Local electricity distributor This is an organisation which owns and controls the principal distribution system in the Distribution District in which the installation is located. In general, it owns and controls the wiring, poles and associated infrastructure which conveys electricity to a consumer. APAM is an Electrical Distributor but never the Local Electricity Distributor.

Low voltage (LV) This is a voltage exceeding 50 Vac or 120 Vdc but not exceeding 1000 Vac or 1500 Vdc


TECHNICAL STANDARD


Acronym Definition

Main switchboard (MSB) This is the first low voltage switchboard between the transformer terminals and the low voltage installation. The MSB is owned by APAM and is the location to establish the one and only connection between earth and neutral.

Main Distribution Switchboard (MDB)

This is a single panel, frame, or assembly of panels on which are mounted, on the face, back, or both, switches, over-current and protective devices, busbars, and instruments. Switchboards may be accessible from the front or rear and have top or bottom cable entry provisions. Where access is restricted, large switchboards are often manufactured in transportable sections for site assembly.

Non - Essential An electrical load that shall:

Experience a mains outage through Short duration mains outages

Experience a mains outage through Medium duration mains outages

Experience a mains outage through Long duration mains outages


Prospective fault level Refers to the maximum current (r.m.s) that is expected to flow into a short circuit at a stated point on an electrical system, which may be expressed in kA or in MVA.

Quality assurance (QA) Refers to a program for the systematic monitoring and evaluation of the various aspects of a project, service, or facility to ensure that required standards and outcomes are met and delivered. This requirement applies to both design and electrical work on site.

Residual current device (RCD)

A circuit-breaking device installed in electrical equipment to protect the operator from electrocution by sensing currents leaking to earth. Circuit breakers with fixed 10mA or 30mA coils are commonly used.

Service equipment

This is the metering and control equipment supplied and installed as specified in either APAM's or the Local Electricity Distributor's service and installation rules. It may include service fuses, circuit breakers, meters, current transformers, and links.

Uninterruptible Power Supply (UPS)

A system for sustaining continuity of mains power to the connected loads during loss of mains power incidents of both Short duration and Medium duration.

5 GENERAL REQUIREMENTS

5.1 Sustainability

Users of this Standard shall demonstrate that consideration for the whole of life has been undertaken

ensuring sustainability has been optimised. Whole of life includes implementation and operation

through to decommissioning and disposal.

Works in accordance with this Standard shall consider both its effect on and how it will be affected by

the following:

Economic.

Social.

Environmental.

Security.

Operation and Maintenance.

The User of this Standard shall make use of historical, current and projected / forecasted information

when assessing the Sustainable Design for the whole of life.

Users shall apply the principles of harm minimisation. Wherein scientific doubt shall not be used as a

reason to avoid undertaking preventative measures.

5.2 Safety in Design

All design and construction activities shall appropriately consider and incorporate safety in design and

construction. This shall include construction work, accessibility, operational and maintenance

consideration. Refer to Work Health and Safety Act 2011 and Work Health and Safety Regulation

2011.

5.3 Fitness for Purpose

All services, equipment and devices to be installed on APAM projects shall be fit for the intended

operational purpose.

Fitness-for-purpose refers to fitness for the specifically intended purpose by APAM in the context of

their existing and ongoing operations.

The fitness-for-purpose shall incorporate the life cycle cost elements of Section 5.4. In particular,

accessibility, maintainability, operational factors to ensure ease of maintenance, minimisation of

energy consumption, economic considerations and effective utilisation of operational personnel.

5.4 Life Cycle Costing

A whole of life view shall be taken for all design decisions taken during the design of LV reticulation

systems. Consequently, the specification and selection of systems, products and materials shall be

considered over a product life cycle and not merely based on initial capital cost. Therefore, Life Cycle


TECHNICAL STANDARD


Costing (LCC) shall consider the initial capital cost, operational costs (e.g. energy usage and cost),

longevity and maintenance costs. This can be described as:

LCC = Cost of (initial capital + repairs + maintenance + operation + energy + disposal)

Where:

Initial Capital Cost includes removal of redundant existing equipment and cabling, design, project

management, installation/construction, testing and commissioning and handover.

Repairs include unplanned non-maintenance activities e.g. broken wires, equipment failure etc.

Maintenance includes such items as recurrent work (e.g. lamp replacement), lubrication, calibration,

software upgrade or replacement. Note that some systems or equipment elements may have a

reduced life compared with the rest of the installation. These need to be replaced at appropriate times

and due allowance is required to be made in maintenance plans and procedures.

Operation relates to those activities that are required to ensure proper on-going functionality of the

installation and equipment. It is important that Designers consider this aspect fully; otherwise

additional downtime, staffing and shift work may be unnecessarily required.

Energy is total energy (usually in kWh) required to effectively operate the plant, system or installation

over their operational life.

Disposal is the activity incurred at the end of the equipment or installation life and includes

demolition, removal from site and appropriate disposal. In addition, some equipment may contain

toxic or hazardous components which may require to be disposed by specialist organisations at

significant cost.

In most instances there are competing products, services and systems available in the market and it

is expected that various options are considered and suitable recommendations and selections made

on a life cycle costing basis. Any design change shall be able to be justified in this way.

LCC is required to consider that equipment or systems may have elements incorporating different

useful lives. It is expected that comparative LCC be demonstrated as the basis for the selection of all

systems, products and materials when fitness-for-purpose has been established.

Refer to AS/NZS 4536-1999 Life Cycle Costing for guidance of what factors shall be considered in

assessing life cycle costs.

5.5 Maintainability

All LV electrical systems and equipment shall be designed to easily facilitate safe and efficient

maintenance to be carried out by competent APAM staff and Licensed Electrical Contractors.

Due consideration shall be made regarding equipment location and clearances to ensure safe

working practises can be implemented during routine maintenance.

Ensure that all As-Built documentation and Operation and Maintenance manuals are created or

updated as part of the project works.


TECHNICAL STANDARD


5.6 Testing and Commissioning

Prior to permanent connection to supply, all installation work carried out shall be tested, and a test

report completed and forwarded to the relevant Electrical Inspector and APAM’s Electrical Authority.

This shall be carried out by the installing Registered Electrical Contractor (or another electrical

contractor engaged by the installing electrical contractor to undertake this work on their behalf).

The tests are required to check that the installation is safe and that it complies with the relevant

Australian Standards. APAM may also specify additional particular tests for individual projects. Refer

to AS/NZS 3670 – in-service safety inspection and testing of electrical equipment.

Testing shall also be undertaken in order to verify compliance with all legislation, standards and

requirements.

After testing is completed, all electrical installations, systems and sub-systems shall be commissioned

in accordance with a check list of actions or activities that are specifically developed for the project.

Note that the Contractor shall undertake all relevant pre-commissioning tests prior to inviting

appropriate parties, including APAM, to witness site testing and commissioning.

Confirm that circuit protective devices are sized and adjusted as required to properly protect the

installed circuits and electrical network.

Three-phase electrical installations shall be tested at all three-phase switchboards and three-phase

outlets to ensure proper phase sequence is present; if not, modify to achieve this.

All commissioning results shall be documented in a clear and concise manner stating the measured

values obtained (where relevant), set points and alarm status, as well as other required features and

whether the tests passed or failed, or what remedial action was taken. The results of the testing and

commissioning shall be bound in a report, a copy of which shall be forwarded to APAM.

If installation or system failure is observed during testing and commissioning, after modifications are

effected, re-testing shall be repeated until satisfactory outcomes and installation or system operation

are achieved and documented as described above.

Allow a minimum of one week’s notice to inspect any work that is to be concealed to enable

photographic records and measurements to be taken.

5.11 Electrical Service Level

Electrical Low Voltage Systems are designed to align with the overall airport power network. It is vital

that electrical loads are supported by the appropriate infrastructure to ensure an appropriate

continuity of electrical supply.

APAM recognises four categories of outage based on the duration of loss of mains.

Short Outage Medium Outage Long Outage Extended Outage

DURATION ms to seconds

< 180 seconds

Seconds to

minutes

180 s to 10 m

Minutes to Tens

Of Minutes

10 m to 45 m

Longer than

45 minutes

> 45 m

POSSIBLE CAUSE

Dips, sags, upstream switching

Trips, switching failure, network problems, faults.

Transformer failure, busbar or

network problems, faults.

Zone transformer failure, major

network problems.

The design of airport – wide electrical systems is based on having two HV networks, one of which has

standby generators providing essential power over a HV network.

Some substations are equipped with dual transformers, one of which is powered via the network that

is supported by the generators. This is designated the “Essential” supply transformer.

It is understood and accepted that certain load categories can and will experience a mains outage for

the time it takes for the generator supply to be switched automatically through to the LV load

switchboard. Other load categories can and will experience a mains outage for periods while

automatic transfer switches operate to reinstate mains power. Still other load categories can and will

experience a mains outage for longer periods where the time without power is the time required for

the networks and transfer switches to be manually reconfigured.

The most critical loads must be supplied via an uninterruptible power supply that automatically

bridges the loss of mains power until such time as the generator supply is switched automatically

through to support the LV load.


TECHNICAL STANDARD


6 DESIGN PHILOSOPHY

This section describes the fundamental design philosophies to be used in designing or augmenting

the LV reticulation systems for APAM. This Standard shall be read in conjunction with the HV

Reticulation Design Standard, which covers the specific requirements for substations and HV

networks.

The design philosophy for the APAM LV reticulation system within the Terminal Buildings is based on

a 3 level distribution system, which provides a distributed load centre arrangement. The 3 distribution

levels comprise of:

Level 1 HV/LV Substation and Main LV Switchboard.

Level 2 Distributed Main Distribution Switchboards.

Level 3 Final Distribution Boards.

Figure 1 - LV Distribution Philosophy

6.1 Service / Consumer Mains

Service / Consumer mains shall be provided between the main LV switchboard (MSB) and the

transformer terminals. Service / Consumer mains shall be designed in a similar manner for both the

Essential and Non-essential services. Mains cabling shall be reticulated overhead on suitably sized

cable trays / ladders or underground using cable trenches / pits / conduits. The total overall length of


TECHNICAL STANDARD


mains cabling shall be kept to an absolute minimum to minimise the total volt drop across the cable.

The maximum allowable volt drop across mains cables shall be less than 1%.

Service / Consumer mains shall be sized in accordance with AS/NZS 3008.1.1:2017 and fully rated to

the installed substation / transformer capacity.

Service / Consumer mains shall be designed to achieve a minimum classification of WS52W in

accordance with AS/NZS 3013-2005.

6.2 Main LV Switch Rooms

All main LV switchrooms will be ventilated or cooled to maintain internal room temperatures below

25°C during normal operating conditions.

All main LV switchrooms will be constructed to provide a minimum fire rating of FRL 120/120/120 and

sized to provide clearances in accordance AS/NZS 3000:2007.

Figure 2 - Typical LV Switchroom Layout - Option 1


TECHNICAL STANDARD

6.3 Electrical Service Level

6.3.1 SAFETY SERVICES

The term “Service Level” as used by APAM does not change or reduce in any way the requirements

for “Safety Services” as defined by AS 3000 1.45.104

6.3.2 SERVICE LEVEL

APAM designates all electrical loads into the following categories of Service Level.

SERVICE LEVEL Short Outage Medium Outage Long Outage Extended Outage

CASA Must stay ON Must stay ON Must stay ON Must stay ON

Aero Critical Must stay ON Must stay ON Must stay ON Must stay ON

Aero Essential Outage acceptable Must stay ON Must stay ON Must stay ON

Aero Non-Essential

Outage acceptable Outage acceptable Outage acceptable Must stay ON

Business Park Outage acceptable Outage acceptable Outage acceptable Must stay ON

Loads that are required to stay ON during an extended outage must at least be supported by manual

switching to alternative equipment options and/or manual connection to standby power generation

equipment. If necessary, designs must include permanent provisions for portable standby generators

to be manually but speedily connected to the load.

Loads that are required to stay ON during a long outage must at least be supported by permanently

installed automatic standby power generation and manual changeover switching.

Loads that are required to stay ON during a medium outage must at least be supported by some form

of automatic change over to an alternative LV electrical supply.

Loads that are required to stay ON during a short outage must be supported by some form of

automatic uninterruptible LV electrical supply such that the load is fully supported. This is in addition

to the backup systems that are required to provide support for the longer duration events. For

example, Aero Critical loads will require UPS backup along with connection to a generator supported

essential network as well as automatic switching of power to ensure continuity of supply. A minimum

battery support of 20 minutes (10 minutes outage plus a further 10 minutes for switching contingency)

must be provided, longer if required by the characteristics of the project.

6.9 Final Circuit Wiring

Final circuit wiring shall be in accordance with AS/NZS 3000, developed for an MEN System.

Designers must accommodate the necessary short circuit current and fault loop impedance for

effective operation of circuit protective devices (CPD) and ensure that the volt drop in the earth-

neutral return path is less than 50V under fault condition. This may be required for reduction of fault

loop impedance to ensure effective operation of the CPD within the required automatic clearing time.

Minimum size cables for power circuits shall be 2.5mm². Upsize as required by AS 3008.

Minimum cable size for lighting circuits shall be 2.5mm².

Minimum size control wiring is 1.5mm².

A separate fully sized neutral shall be run with each circuit. When sizing neutral conductors

consideration shall be given to the presence and impact of harmonic currents.

The maximum voltage drop on final circuits shall not exceed 1.5% of the nominal voltage, unless

specifically approved otherwise by APAM. Normally approval will be given if the length of the final

circuit is longer than usual or if the installation’s electrical load is small and the total voltage drop does

not exceed 5% or 7%.

6.9.1 Cable Sizing

Cables shall be selected in accordance with AS/NZS 3008.1.1, based on:

current carrying capacity, taking into account de-rating factors for “method of installation”, “grouping of circuits” and “external influences”

earth fault loop impedance

voltage drop

cable short circuit rating

Working calculations for cable selection shall be provided to APAM.

The cable size selected shall concurrently address both volt drop requirements and fault current

design needs and the ability of circuit breakers to trip on overload and fault (i.e. cable sizes may need

to be larger on long cable runs).

6.9.2 Cable De-Rating Factors

Particular attention is required regarding the de-rating of cables where these are bunched or grouped

together on cable routes or at congested cable areas such as switchboards.


TECHNICAL STANDARD


Conduits and cables shall be arranged in such a manner as to permit sufficient space between them

for the cooling of the cables and to provide the required current rating without being affected by:

heating from other current carrying conductors

self-heating due to inadequate air circulation around the cables

Specified cable ratings for stated cable sizes shall be maintained throughout the cable routes by

utilising the appropriate spacing and installation method, as determined from AS/NZS 3008.1.

6.10 Redundant Services

All redundant LV services comprising of sub-mains, switchboards, distribution boards, final circuit

wiring and accessories shall be in isolated, disconnected, stripped-out and removed from site as part

of any redevelopment and refurbishment project. Under no circumstances are redundant services to

be left within the installation.

6.11 Documentation, Quality Assurance and ongoing

Maintenance

When an electrical project is implemented, it is normally part of a larger project, which may be a new

build project, a property/facilities project, part of an expansion or refurbishment, or relocation.

Regardless of the project type, each electrical installation must be fully documented and recorded to

ensure that it has the visibility and understanding of the larger Facilities and IT teams and their

consultants.

Details are to be provided in relation to ongoing and pro-active monitoring of each facility. Based on

this, it is intended that the monitoring of all facilities is standardised as specified to ensure that APAM

Facilities staff know what is being monitored and how it is being monitored. IT and Facilities staff will

approve details of the monitoring system during planning and implementation activities.

The project responsible for the implementation of the facility into the Airport Precinct must ensure that

details of all assets are properly recorded and captured. Asset capturing of equipment and systems

deployed into the facility should be included and incorporated with existing asset capturing and

management regimes, and reviewed by IT Facilities by the planning and implementation teams.

The project implementing the facility should ensure that drawings fully describing the new space, how

this incorporates into other spaces, including how all facilities interconnect should be updated and/or

provided and if feasible, incorporated in the Airport mapping systems, including location information

for each facility on the mapping system. The final layout map will be approved by APAM, as would

any subsequent additions.

As built drawings for each facility shall be provided to APAM. The following is the minimum

documentation that must be provided for approval during the design and construction stages and in

“as-constructed” versions prior to hand over:

7 OPERATIONAL PHILOSOPHY

Melbourne Airport’s Low Voltage (LV) network comprises multiple HV/LV substations distributed

around the airport to service various load centres. These substations operate at 22kV with

transformers stepping the voltage down to 400V.

Three main terminal high voltage substations; Sub 1 (Terminals 2 and 3), Sub 100 (Terminal 1) and

Sub 200 (Terminal 4) include essential bus (mission critical loads such as life safety, security and

aviation operations) and non-essential bus (non-critical loads).

The essential bus is supplied with backup generators in case of mains failure;

Sub 1 and Sub 100 backup generation consist of diesel generators which operate in island mode during mains failure (and briefly in parallel during restoration of load to mains supply).

Sub 200 generators (tri-generation plant) are designed to run either in island mode (for backup power supply) or in parallel with the mains.

During mains failure, the PLC load management system will shed all loads, and then incrementally

stage essential loads on as generator power is available. During mains return the generators

synchronise to mains for a seamless transfer.

Within the Terminal Precinct, HV substations are configured with an Essential HV-LV arrangement

and Non-Essential HV-LV arrangement that can be bus-tied at either HV or LV for operational

requirements. The substations are sized so that during bus-tied arrangement they cannot be

overloaded in an N-1 configuration.

Switching between LV essential and non-essential mains switchboards are also performed through

make-before-break switching procedures. Make before Break switching is only performed by APAM

HV operators. Three pole transfer switches are employed. All switching is carried out by APAM or

APAM’s approved facility manager with an approved switching method statement. Provision for HMI /

remote switching facilities is to be considered during design development. This procedure results in

the need for higher fault rated main switchboards (100kA for 1 second).

The overall design philosophy is that the airport must continue to operate under mains failure

conditions. It is accepted that this operation will be under reduced standards. To this end the following

loads must be connected to an essential circuit:

All life safety services (FDCIE; control rooms; fireman’s lifts; smoke extraction fans; staircase

pressurisation fans; etc.)

All emergency and EXIT lighting.

50% of all common area lighting.

All apron services.

All baggage handling services.

All air handling services including toilet extraction systems.

Small power connections to loads such as ticketing equipment

UPS supplies, including internal and external bypass circuits.

All cooling equipment for control rooms and ITS rooms.


TECHNICAL STANDARD


All CASA and Border Protection DB’s.

Hearing augmentation equipment (if not on UPS circuits)

The following loads must be connected to a UPS circuit:

All ITS Room circuits except lighting and HVAC.

All SCADA equipment.

All HVAC, MSB and MSSB controls.

All BMS equipment.

All EACS equipment.

All Wi-Fi equipment

Apron lighting

All DAS equipment

All PID equipment

All security scanning equipment

Metering equipment and infrastructure

The Airport requires energy usage to be comprehensively metered and to this end two site wide

metering systems are deployed. The first carries out revenue metering for energy cost recovery while

the second provides APAM staff the ability to check usage, balance energy accounting, and

determine usage by major load groups. All loads are to be metered in one or more ways, including:

Revenue metering (for onward billing).

Check metering

Energy metering for tuning and efficiency purposes.

Detailed Metering requirements are set out in this document and the various specialist technical

specifications.


TECHNICAL STANDARD


8 ELECTRICAL SUPPLY

8.1 General

8.3 Load Rating

To match maximum transformer rating within connected substation.

8.3.1 Spare Capacity

Minimum of 25% spare capacity.

8.4 Fault Rating

It is the Designer’s responsibility to determine the fault levels for the purposes of specifying the

appropriate electrical equipment and system capability.

The prospective fault level shall be based on APAM requirement to parallel transformers during the

‘make before break’ switching operation.

8.5 Supply Quality

8.5.1 Power Factor

The minimum system power factor at the common point of coupling shall be no less than 0.9 lag.

8.5.2 Harmonics

Three types of metering are required:

1. Revenue metering

2. Energy monitoring

3. Check metering

Refer to details set out in the Metering Chapter in this document.

8.7 Load Shedding

The intent of the load staging scheme is that, in the event of a supply outage, site essential loads can

be supplied from the on-site generation as the generation is brought up to full output. In the case,

essential loads most critical to life safety and airport operations will be reinstated first. Load staging

will then progressively reconnect lower priority essential loads, until the maximum amount of essential

load is supplied by the on-site generation.

The load priority designed within the LV reticulation system shall be in accordance with the Table 1

listed in the APAM Load Staging Priority Order document.

All projects with new essential load requirements shall engage Systems Insight to review and update

the Load Staging Priorities in conjunction with APAM HV.

8.8 Surge Protection

Electronic surge protection devices (SPD) shall be installed in the LV electrical system to ensure

safety of people, protection of equipment and continuity of supply.

SPDs shall be installed near to the origin of the installation or in the main LV switchboard. Additional

SPDs may be necessary to protect sensitive equipment and external services which have a high risk

of lightning strike. These secondary SPDs shall be coordinated with the primary SPD.


TECHNICAL STANDARD


8.9 Electro-Magnetic Compatibility (EMC)

The electromagnetic environment surrounding the LV installation is particularly challenging in that the

airport is surrounded by radio, radar and various fixed and mobile transmitters.

AS/NZS 61000 does not identify a specific category for airports. LV equipment supplied shall have an

electromagnetic compatibility level suitable for a location Class 6 (as defined by AS/NZS 61000.2.5)

with the added requirement that the following will be in close proximity:

Broadcast transmitters located within 100 m.

Powerful mobile transmitters (both handheld and aircraft based).

Wi-Fi access points.

Radar transmitters within 1.5 Km.

Various LV electrical mains cables

Substation within 100 m.

On-site standby generation.

Any vermin or bird proofing shall have appropriate hinged access gates with locks at appropriate

centres to enable maintenance access.

Cable trays shall be run in such a manner as to follow the structural members of building. Tee-offs

shall be implemented in a manner that has minimum visual impact on the building or facility in which

they are installed.

The height and disposition of cable tray runs shall give due consideration to safe and easy

accessibility by ladder, preferably located so access can occur without impact to public, occupied or

tenancy areas.

Cables shall be neatly installed on cable trays, utilising proprietary straps and fixings. Cable spacing

shall be in accordance with AS 3008 and de-rating shall be avoided. A 25% spare capacity shall be

provided.

Segregation of cable systems is an important design issue that needs to be carefully considered to

ensure the correct de-rating factors are applied during cable sizing.

Suitable cable tray and ladder supports shall be installed to manufacturer’s recommendations and

instructions, and shall adequately carry the anticipated cables load for the present and future, with

minimum deflection.

9.3.2 Underground

Service mains installed underground shall have the route identified by suitable markers. In addition,

suitable “as-built” drawings shall be provided to accurately record locations in 3D, as well as access

points, change of direction, electrical elements, pits, jointing boxes.

The philosophy for underground cable route marking and identification shall follow the arrangements

detailed in the following standards;

AS/NZS 3000.

Mains cables installed underground shall be enclosed in conduit, for mechanical protection, from the

point of supply to the Main LV Switchboard. Conduit shall be “weather set” at the Point of Attachment

and securely saddled as required by AS/NZS 3000.

Cables run underground shall comprise single core double insulated cable, enclosed in heavy duty

rigid UPVC conduit of 150mm minimum diameter, suitably sealed to prevent ingress of water.

Suitable pits (with covers) shall be installed to assist with installation of mains cables. These shall be

suitably sealed, drained and where possible located above water collection points. Pits shall be

interconnected and accessed by means of appropriate heavy duty UPVC conduits.

Pits are required to address a number of practical site conditions, which include the following:

suitable and accessible LV pits, with a type and dimensions to Civil design for specified

minimum bend radius.

maximum spacing between pits to suit pulling tension of the cable types and size

bell-mouthed ducts

pass below the upper level of the pit or ground level.

9.3.3 Diverse Paths

Essential and non-essential cables shall be segregated and reticulated via completely diverse paths

up to the point of termination / equipment location, so that adequate security of supply for critical

supplies is provided.

As a general rule a minimum horizontal separation distance of 2m shall be provided. In instances

such as service tunnels, which have a reduced width, then where possible the following “diagonally

opposed” philosophy will be implemented. Where this is not possible due to other services, then high

and low level reticulation routes are to be used to maximise separation distances.

10 PROTECTION & DISCRIMINATION

10.1 Prospective Short Circuit Current (PSCC)

To determine the required fault capability of switchboards and associated equipment Designers shall

determine the prospective fault levels at the required switchboard locations.

It is the Designer’s responsibility to determine the fault levels for the purposes of specifying the

appropriate electrical equipment and system capability.

For new works. Designers shall provide working calculations to APAM to demonstrate that the

appropriate equipment and switchgear has been specified. Calculations shall be made at all required

switchboard locations (including mechanical services switchboards and others, as may be required).

In this regard, documented data in the form of either calculations or measurement of both maximum

and minimum symmetrical three-phase fault and phase-to-earth fault levels shall be provided.

Where a design is connected to existing circuitry/installation a recalculation of all fault levels for all

affected parts is required.

10.2 Protection

10.2.1 Air Circuit Breakers

Air circuit breakers (ACBs) shall be used on all circuits with a load rating greater than 800Amps.

All ACBs shall be provided with fully adjustable electronic trip units providing the following functions

as a minimum:

Current Setting (Long Time) – Ir,

Tripping Delay (Long Time) – tr,

Pick-up (Short Time) – Isd,

Tripping Delay (Short Time) – tsd,

Pick-up (Instantaneous) – Ii.

All ACBs shall be fully withdrawable

10.2.2 Moulded Case Circuit Breakers

Moulded case circuit breakers (MCCBs) shall be used on all circuits with a load rating between

100Amps and 800Amps.

All MCCBs shall be provided with fully adjustable electronic trip units providing the following functions as a minimum:

Current Setting (Long Time) – Ir,

Tripping Delay (Long Time) – tr,

Pick-up (Short Time) – Isd,

Tripping Delay (Short Time) – tsd,

Pick-up (Instantaneous) – Ii.

All Essential MCCBs shall be fully withdrawable.


TECHNICAL STANDARD


10.2.3 Miniature Circuit Breakers

Miniature circuit breakers (MCBs) shall be used on all circuits with a load rating less than 100Amps.

MCB minimum breaking capacity shall be => 10kA

MCBs shall be DIN-T type

MCBs shall provide the option for integral MCB/RCD functionality, with RCD trip sensitivity of 30mA or

100mA depending on application.

10.2.4 Cascade Protection

Cascade protection is the use of the current limiting capacity characteristics of an upstream circuit

breaker to permit installation of lower-rated and therefore lower-cost circuit breakers downstream.

Cascading can only be used as part of the design when supported by manufacturer’s laboratory tests

and circuit breaker cascade protection tables. Circuit breakers must be from the same manufacturer

and selected in accordance with the cascade tables.

The use of a protective device possessing a breaking capacity less than the prospective short-circuit

current at its installation point is permitted as long as another device is installed upstream with at least

the necessary breaking capacity.

In this case, the characteristics of the two devices must be coordinated in such a way that the energy

let through by the upstream device is not more than that which can be withstood by the downstream

device and the cables protected by these devices without damage.

10.3 Discrimination

The design philosophy shall provide full energy discrimination of all circuit protective devices (CPD) in

series with one another.

The technique of circuit breaker protection coordination that is dependent on the characteristics of the

CPD as permitted by Clause 2.3.4.5 of AS/NZS 3000 must be supported by data obtained from the

manufacturer’s type testing of the devices and accepted by APAM prior to implementation.

Designers shall provide a detailed discrimination study and or sufficient working calculations and time-

current curves and such other necessary information required to demonstrate that correct

discrimination has been achieved between upstream and downstream protective devices.

10.4 Selectivity

The importance of achieving discrimination between protective devices is that selectivity is introduced

in LV system protection. Selectivity is required to ensure that, where a number of protective devices

are effectively in series, the protective device closest to a fault interrupts the circuit first, thus

minimising system disruptions.


TECHNICAL STANDARD


11 METERING

11.1 Approach

The Airport requires energy usage to be comprehensively metered and to this end two site wide

metering systems are deployed. The first carries out Tariff/Revenue metering for energy cost recovery

TECHNICAL STANDARD


13 EARTHING & BONDING

13.1 General

Earthing and bonding arrangements shall be provided in accordance with AS/NZS 3000:2018 to

perform the following functions enabling the safe operation of the electrical installation:

Enable automatic disconnection of supply in the event of a short- circuit to earth fault.

Enable automatic disconnection of supply in the event of excessive earth leakage current.

Enable equipment requiring an earth reference to function correctly through functional earth (FE) arrangements.

Equipotential bonding between extraneous conductive elements to mitigate voltage differences between exposed conductive parts of the installation.

Provide an effective and reliable low impedance fault path capable of carrying earth fault and earth leakage currents without danger or failure from thermal, electromechanical, mechanical, environmental and other external influences.

13.2 MEN Earthing System

The protective earthing system required to be installed within APAM’s facilities is to be a multiple

earthed neutral (MEN) distribution system. The MEN earthing system will be provided in accordance

with AS/NZS 3000:2007 and is the usual earthing system used in Australia.

Under the MEN system the neutral conductor of the distribution system is earthed at the source of

supply, at regular intervals throughout the system and at each electrical installation connected to the

system. Within the electrical installation, the earthing system is separated from the neutral conductor

and is arranged for the connection of the exposed conductive parts of equipment.

The MEN system as a TN-C-S system with the letters signifying-

T the distribution system is directly connected to earth at the neutral point of the supply

transformer

N the exposed conductive parts are connected to the earthed point of the distribution

system-at the MEN connection

C the neutral and protective conductor functions are combined in a single conductor (the

neutral conductor of the distribution system)

S the protective conductor function is separated from the neutral separate conductors

within the installation.

13.2.1 Protective Earthing (PE)

Fault protection by means of automatic disconnection of supply is intended to limit a prospective

touch voltage may arise between simultaneously accessible conductive parts during fault conditions.

Automatic disconnection during fault conditions is achieved by:

the provision of protective earthing (PE) in which exposed conductive parts are connected via conductors or similar medium to the earthed neutral of the distribution system; and


TECHNICAL STANDARD


in the event of a fault current or excessive earth leakage current flowing in the protective earthing system, overcurrent or earth leakage current protective devices (RCDs) operate to disconnect the affected part of the installation within the specified time and touch voltage limits.

13.2.2 Functional Earthing (FE)

Sensitive IT Equipment may require connection to a ‘clean earth’ system for purposes of correct

operation rather than the safety conditions associated with protective earthing.

In such cases functional earthing (FE) conductors are not required to be selected and installed to

withstand fault currents or to be identified in the same manner as a protective earthing conductor.

Functional earthing (FE) conductors shall be insulated from all protective earthing conductors and

shall only be connected together at the Main LV Earth Bar within the substation.

Functional earthing conductors will be provided in accordance with AS/ACIF S009

(Telecommunications Reference Conductor) and colour coded and clearly labelled to avoid the risk of

cross connection with the protective earthing system.

13.2.3 Earthing Conductor Size (csa)

The cross-sectional area (csa) of a protective earthing conductor shall be sized in accordance with

AS/NZS3000:2007 Clause 5.3.3 and will provide the following characteristics:

adequate current-carrying capacity for prospective fault currents for a time at least equal to the operating time of the associated overcurrent protective device; and

appropriate earth fault-loop impedance; and

adequate mechanical strength and resistance to external influences.

The minimum cross sectional area (csa) of a protective earthing conductor shall be in accordance

with Table 5.1 of AS/NZS 3000:2007.

The selection of copper or aluminium conductors shall be assessed in accordance with potential risks

associated with dissimilar metals and bi-metallic corrosion, especially when considering earthing

conductors for equipotential bonding purposes.
