(e) Any salvaged fuses following a fault are to be confirmed serviceable by testing with a Micro-ohm-meter. If the fuse resistance is proved to be within the nominated limits, the fuse may be reused and included in an identical set of fuses for future use. (If the fuse resistance is outside the nominated limits, the fuse may have deteriorated and is to be discarded.)

9.23 PLANNED OUTAGE STANDARD

(a) General:

Energex is committed to delivery of high quality uninterrupted supply of electricity to its Customers. (i)The standard of supply is measured by, reliability targets and is guaranteed to Customers through Guaranteed Service Levels (GSL’s) and monitored through level of Customer complaints received.

In order for Energex to achieve uninterrupted supply of electricity targets, all works requiring access to (ii)the distribution network or Commissioning new infrastructure onto the distribution network, is not to result in an interruption of electricity supply to Customers, unless it is impractical to do otherwise. In cases where planned interruptions are unavoidable to undertake works, initial applications for interruptions to supply will be assessed by the appropriate Energex Officer (e.g. the Low Voltage Outage Officer, Contract Officer or Commissioning Coordinator) to determine whether the interruption can be practically avoided.

Distribution of network constraints may determine the time when switching can occur. The Energex (iii)Commissioning Coordinator may determine the most suitable time for switching.

Where an interruption to Customers cannot be avoided by the use of LV ties, live work techniques or (iv)generator deployment; limit planned outages to 1 outage between the hours of 8:00 am and 4:00 pm.

Note: When generators nominated to be used to avoid a planned outage and minimise Customer inconvenience; this excludes Customers within immediate Worksite.

Exception from generator deployment at a Worksite is when a situation occurs where it is impractical (v)from an engineering / construction prospective or an unsafe situation will occur.

(b) Commercial and Industrial:




ABN 40 078 849 055

Electricity supply to commercial and industrial Customers cannot be interrupted during their normal (i)hours of business without their prior consent.

Longer outage duration is acceptable if negotiated with all affected Customers and have their written (ii)agreement.

9.24 SAFETY TAG AND LOCKOUT

(a) Ensure the effective safe tagging and lockout of all energy sources where inadvertent activation or deactivation of control mechanisms are to be implemented to reduce the risk to Operators or plant.

(b) Manual 00301 and the Queensland Electricity Entity Procedures for Safe Access to High Voltage Electrical Apparatus (SAHV) details procedures for working on the de-energised Energex network.

9.25 PERSONAL PROTECTIVE EQUIPMENT – WORKING ON ENERGISED ELECTRICAL EQUIPMENT

(a) While performing any work on energised electrical equipment or working in Proximity to exposed live parts of the Energex network, ensure the safe system of work includes the following:

Eye protection is worn (Non-metallic). (i)

Correct class of insulating gloves also worn when: (ii)

Performing any HV manual switching work.

Operating ground controlled plant (for example, GP trucks).

(b) At all other times the wearing of insulating gloves is to be determined by the Service Providers safe system of work, excluding the situations outlined above.

9.26 EWPS USED IN HV LIVE WORK

Term Definition

EPP System The Energex electrical partners’ portal system that records work undertaken and confirms notification obligations are met for individual planned interruptions to Customers’ electricity supply which are being managed by the Energex Service Providers. The system is provided externally via the Internet (web portal).

Clear Business Day This is a full Business Day occurring between the completion of all Customer notifications and the commencement of the planned interruption. In this instance, a local Authority public holiday is considered to be a Business Day should it occur on a Monday to Friday inclusive. (A Queensland state wide statutory holiday is not a Business Day).

Responsible Person An effected Customer (resident /tenant) over the age of 18 years.

SANS System Energex system for the management and recording of planned interruptions to small areas of Customers that do not require switching of the electricity network (Small Area Non-Switched). The system is provided externally via the Internet.

Appendix A – Declared Non-Live Tasks

Declared Non-Live Tasks A1

The Electrical Safety Regulation 2013 places restrictions on the performance of live work and only allows it where it is not practicable to perform the work de-energised and the work can be done safely. These tasks have been assessed to have an intolerable risk when performed live. Energex has declared that due to this intolerable risk the following activities will only be performed de-energised.

S.E.A.Q. Concrete Pillar

Declared Non-Live Task. Not to be worked on live by any person

NGK LV ABC bundle box to which restrictions apply.
