Earth leakage protection systems with self-reclosure

Given the necessity and obligation of ensuring effective protection to both people and goods and the complexity of installations requiring continuous supply of electrical energy without removing earth leakage and overload protection, CIRCUTOR has developed a range of equipment which allows safety to be matched with continuous service. Self-reclosure is the ideal solution for installations requiring continuous supply of electrical energy without the usual maintenance staff:

Rural installationsRefrigerated chambersPublic lightingMobile telephone repeatersTraffi c lightsTunnel lightingATM’sCable televisionetc.

In every self-reclosure system the type of protection to be reconnected and under which conditions must be known.

•••••••••

Self-reclosure systems operate under:

Earth leakage current (differential)Earth leakage current (differential) + overload and short-circuit (overload)

Elements comprising a self-reclosure system

Self-reclosure relay

Self-reclosure relays offer additional benefi ts (self with closure, overload or short-circuit protection), to the reliability and safety shown by Series U earth leakage protection.

Its functions are:

Fault detection (earth leakage or overload) via a signal generated by the transducerAnalysing if this fault should set off an alarm, with regard to the different preset parametersOperating on a power device which connects – disconnects the load from the system

Breaking element

The breaking element always operates as a power switch which supports the line power to be protected and is outside the relay.

The breaking elements which may be associated with self-reclosure relays are:

Motorised overload/short-circuit device (MT series) (see page 24)ContactorCircuit breaker with remote-control (MCB) (see page 23), with the double function of overload/short-circuit protection

and contactor (the conduct of function is bistable)

The features which the breaking elements must know are:

Rated current (in the contactors)Rated currents and the protection thermal curve (in overload/short-circuit devices)Features of the command inputs in the operating elementCut off powerNA or NC auxiliary signalling of the status of the breaking device

Parameters related to self-reclosure relays

Indicators associated with protection are different for instant tripping and sealing. Indications are from the same relay (LED) and as an option may be through auxiliary contacts.Another type of display, depending on the relay, is the instant leakage value and the total number of reclosures.

Relay status indication

Typical values:Earth leakage protection 30 mA – 3 AOverload protection 6 A – 63 A.

Rated tripping point for protection

Minimum time which the earth leakage must last to cause the relay to trip.Typical values. 20 ms – 1 s

Timing (delay) for reclosure

This is the time the relay takes from the trip to reclosing.This time may be lineal or exponential.

Time between reclosures

Number of relays with output contact sealing NA or NC

Output relay

The reclosure relays automatically require a permanent auxiliary power supply to be able to manage the automatic connection. Standard value:230 V a.c..± 15 %.Optional 48 V a.c.,110 V a.c., 400 V a.c..

Relay power supply and tolerance

Each relay allows a maximum number of the closures before being sealed. This meter may automatically put on zero if the number maximum number of reclosures has not been exceeded during a preset time (return to zero a time for the reclosure meters).This number will be different for the type of reclosure.

Number of different reclosures / Number of types of reclosure

In order to avoid tripping being mounted up which do not belong to the same fault, a return to zero time for the reclosure meter may be set. This time restarts after each reclosure whenever a maximum number of reclosures is not exceeded.Example: The WRU 25 RA relay has a maximum number of six reclosures before being sealed.

In an installation where the transient earth leakage fault lasts for 50 s, the relay will trip 4 times and reclose 3 times (8 s + 16 s + 30 s). While the third reclosure is being timed the fault disappears so the relay stays on ON. At this time the meter returns to zero reconnections. The RESET option restarts the relay returning the reclosure meters to zero.

Return to zero time for the reclosure meters

The automatic earth leakage reclosure relays offer the same benefi ts as the U series earth leakage protection, among which is the option to check the proper operation of the relay using on-site TEST and RESET using the keypad on the relay itself and remotely using the specifi c inputs.The test is interpreted by the relay as an external leak. The relay will reconnect after a given time and increase the internal reclosure meter. The reset option restarts and relay return in the reclosure meters to zero.

On site and remote Test and Reset (using the keypad)

In the majority of cases (95 %), when the earth leakage protection is tripped, a simple manual reconnection solves the problem because there is no permanent leakage.

If there is no REC automatic reconnector, this simple, manual reconnection operation may become a serious problem if there is nobody nearby or if the earth leakage trip is not known:

• Food rots in the fridge• Plants wither through lack of watering• Swimminutesg pool water goes bad• The alarm system does not protect• The tilting garage door does not work• The farm may suffer serious damage• There is no mobile telephone coverage (fault with t h e telephone repeater)• The ATM does not work• Streets and squares remain in the dark• Traffi c lights stop working• etc.

EARTH LEAKAGE AND OVERVOLTAGE PROTECTIONOVERLOAD AND EARTH LEAKAGE RECLOSURE

BREKING ELEMENT: MT

The RGST-2 / RGST-4 is equipment which protects against permanent overvoltages.

This continuously measures line voltages and if the value in any phase exceeds the previously set limits, either by a maximum or minimum voltage, the RGST set associated with a breaking device (MT series motorised overload device or similar) interrupts the electricity supply. After a certain time, it tries to reconnect again. Also the RGST, with a WG series transformer is an earth leakage protection relay. The RGST, connected to a motorised overload device allows reclosure in the event of an earth leakage and/or overload trip.

RRM-P, RRM-C

The RRM is a relay for overload protection reclosure. It allows the control, remote signalling and remote-control of the associated motorised overload switch (MT and MT-FDE series).

The functions of the RRM relay are:Motorised overload device control:

- Self-reclosure - Remote connection/disconnection (not reconnectable)

Signalling: - On site via LED - Remote signalling using relay blocking reclosure in RRM-P - RS485 communications in RRM-C

Automatic switch remote-control

Features

MCB.P, MCB.T Circuit breaker

The MCB.P or MCB.T our circuit breakers which combine overload functions with contactor functions in the same equipment.The MCB.T version also includes two auxiliary contacts which show the status of the remote control input and the overload input.Both the MCB.P and the MCB.T version include an ordinary contact to indicate a trip from an overload device or from the manual action of the circuit breaker.

There are two trip conditions for the circuit breaker:

Tripping from overheating, delayed, (overload protection)Rapid tripping, electromagnetic (protection against short-

circuiting)

••

Remote-control operates on the same complex as the overload device, guaranteeing disconnection for any event by remote control after manual or overload device tripping. The remote control operates electro-magnetically, applying a control voltage lasting 20 ms, to the ON terminals (Terminals 1-3) and OFF terminals (Terminals 2-3).

It includes an optical displays of the system status (red = ON, green = OFF), regardless of the cause of the trip.
