    The start signals can be used for blocking co-operating protection relays and signalling. Fig. 3.3.-1 and Fig. 3.3.-2 represent REF 610 with the default configuration: all trip signals are routed to trip the circuit breaker. In Fig. 3.3.-1, the residual current is measured via a core-balance current transformer and the output contacts are connected to enable the use of the auto-reclose function.

Trip-circuit supervision The trip-circuit supervision (TCS) detects open circuits, both when the circuit breaker is open and closed, and trip-circuit supply failure. The trip-circuit supervision is based on the constant current injection principle: by applying an external voltage, a constant current is forced to flow through the external trip circuit.

    REF 610 1MRS 755310 Feeder Protection Relay Technical Reference Manual closed. The opening contact, on the contrary, is to be connected in series with the external shunt resistor, which will enable trip-circuit supervision when the circuit breaker is open; see Fig. 4.1.5.-1.

  • Page 64: Trip Counters For Circuit-Breaker Condition Monitoring

    The monitoring function consists of four counters, which count the number of trip signals generated to the circuit breaker by REF 610. Every time a stage generates a trip signal, the corresponding counter value will be increased by one. The number of trips is stored in the non-volatile EEPROM memory.

Fast tripping and initiation of shot 1 using two protection stages In several applications, such as fuse-saving applications involving down-stream fuses, tripping and initiation of shot 1 should be fast (instantaneous or short-time delayed) and of shot 2 and 3, and definite tripping time delayed.

  • Page 139: Fast Tripping And Initiation Of Shot 1 Using Start Signals

    An alternative way to achieve fast tripping and shot initiation (typical for certain countries, such as Finland), is to use start signals from protection stages for shot initiation. The AR function of REF 610 can be initiated by the start signals from stages I> and I >.
