Protection relays forsecondary distribution. SIA

The SIA relays family, composed of SIA-C, SIA-E and SIA-D, are designed to protect the secondary transformationand distribution centres of electrical grids. The protection features include protection against instantaneous andinverse time overcurrent (for the phases and the neutral) as well as an external trip support (temperature, pressure,etc.) depending on the model.

The protection functions can be enabled by using both the front panel and the communications link to the SIComprogramme. Combining the settings and IEC curves available allows for precise coordination with other equipment.

The combination of the available IEC curves and settings allows a precise combination with other equipments.

One of the outstanding features of the SIA-C and SIA-E is the use of the operating current itself for self-powering.This means that maintenance of the transformation and distribution centres is reduced. Neither batteries, chargers,nor any other external power elements are required.

Even more, one advantage over other equipment available on the market facilitates the start-up of installationsand the carrying out specific operations in adverse conditions. All models can be powered from an externalbattery, allowing us to guarantee complete operation of the equipment, including tripping due to any faults thatmay occur.

Overcurrent protectionFunction 50Pinstantaneous phase overcurrent

Function 50Ninstantaneous neutral overcurrent

Function 51PInverse time phase overcurrent

Function 51NInverse time neutral overcurrent

Neutral directional protectionFunction 67NIt uses the residual voltage as the polarisation magnitudeand the residual current as the operating variable. Ifthe directional function 67N is not enabled, it behavesas a 50N Function. The operative time starts when thefollowing conditions are met simultaneously:

- residual voltage higher than setting

- residual current higher than setting

- the gap of the residual current voltage is such thatthe residual current is within the area of theintervention.

External tripFunction 49There is a direct trip input, normally associated with abimetallic contact that is fitted to the power transformer,which serves as a backup for the current functions. Inorder for it to be a real backup, this input is not relatedto the protection processors. This means that theprocessors do not read the input and trip the striker,but the input acts directly on the striker, remainingoperational for as long as the equipment is powered.This input is especial ly protected againstelectromagnetic noise.

Break disconnector protection using triplockingMany transformation centres have a disconnector asa break element. As line breakers have a limited openingcurrent, with short-circuit events at high currents theresponsibility for opening falls on the fuses, becauseotherwise, opening the line breaker would meandestroying it.

In order to deal with these situations, tripping either inphase or neutral is blocked when the measured currentexceeds a preset value.

IEC Curves 255-4/BS-142Standard curves are used for the protection function51 phase and neutral:

- Normally inverse

- Very inverse

- Extremely inverse

- Definite time

SELF-POWERED OVERCURRENT PROTECTION RELAYFOR SECONDARY DISTRIBUTION

Main characteristics

- The SIA-C is a self-powered overcurrent protection relay using the operating current through three /5 or /1standard current transformers fitted on the lines. These transformers are also used to obtain currentmeasurements. The equipment can also occasionally supplied be temporarily supplied by an external battery.

- The events are recorded and a specific test menu is provided.

- High electromagnetic compatibility.

- The installation and subsequent maintenance of batteries is eliminated. The operating costs of the centre arereduced.

- Start-up of the relay from 0.2 times of the nominal current in one phase ensures capacity to trip at low energylevels.

- The line opening mechanism is activated either by means of a striker PRT, operated by the energy suppliedby the relay itself, or by a coil using the TCM trip adapter.

- There are bistable magnetic indicators which indicate the trip cause, maintaining their position even thoughthe relay loses the supply.

HMIThe HMI consists of:

COMMON ELEMENTS (SIA-C, SIA-E y SIA-D)

- A 2x20 LCD screen with alphanumeric characters thatallow the equipment parameters to be set (adjusted)and monitored (measurements, statuses, events).

- A membrane keyboard with six keys that allow you tonavigate the menus and access information of interest.A seventh button - “RESET”, allows you to reset thebistable indicators and the events log. For securityreasons, an access code is needed to modify thesettings.

- LED indicators showing the type of power supply beingused at all times. The relay can use more than onepower source at one time.

- Bistable magnetic indicators that signal the cause oftripping. These indicators remain in position when theequipment loses power, reducing the time themaintenance service needs to identify the cause oftripping.

Test MenuThis allows you to use the HMI to verify correct operation of the LEDs, the bistable magnetic indicators and thetrip contact.

Activating the trip contact from the test menu allows you to verify correct operation of the opening mechanismsimply.

On SIA-D, it is possible to activate the 4 outputs.

EventsEvents are recorded and ordered chronologically (up to 500), allowing you to analyse what has happened withthe installation over time (start-ups, tripping power supplies, etc.). They are recorded chronologically to thenearest millisecond in real time, thanks to the Real Time Clock (RTC). Events can be recorded on a non-volatileRAM memory. This option can be selected according to the model.

21

elementsCommunicationsThe relays have an RS-232 serial port on the front of the equipment with a DB9 connector and an optional rearRS-485 port on connection terminals. The Modbus RTU protocol is implemented for both ports.

The SICom programme with Windows R 2000/XP uses a graphic user interface to allow you to access allequipment information, modify the settings and save events.

The programme can be used locally by using the front port or remotely by using the rear RS485 port.

There are 4 levels of access with user-definable codes.

Self-diagnosisDiagnostic algorithms to generate the corresponding events are executed on starting up the equipment and allthe time the relay is operating.

22

ACCESSORIES

Battery power supply KitComThe KitCom is an adapter that allows you to feed SIA relays from the front communications port, allowing alsoto communicate with the computer locally via RS232.

The power comes from two AA batteries of 1.5 Volts placed at the bottom of the device. The equipment has asmall Dc / Dc power supply raising the voltage to 12 volts required to operate the equipment. This operationincludes the energy necessary to trip. This is important in the commissioning processes of the transformationcentres, allowing full verification of the centre, without any auxiliary power supply.

The equipment has a microswitch that feeds the power supply with a LED (ON) when the voltage is 12 volts.

In addition to all the necessary to give the power supply, this device has two LED associated with the Rx andTx lines of communication, and they are used to verify that there is data traffic between the PC and the SIA relay.

Striker PRTThis is a single effect solenoid. The striker is springoperated.

The striker is activated by low-power polarised electricalsignal supplied by the relay in case of a fault.

The striker is reset to its starting position manually.

Travel: 8 mmSpring strength:

- Start of travel: 37 N- End of travel: 18 N

Response time: 4 msProtection rating: IP-40

Trip adaptor TCMThis item is connected to the relay trip output and suppliesthe energy needed to trip the coil.

It is loaded using the auxiliary 230 Vac voltage of thetransformation centre and retains power for up to 3 dayswithout external power supply.
