The 7SG26 series of relays provides the logical control of a circuit breaker for auto-reclose sequences. The required sequence depends on the substation primary plant arrangement. 7SG26 relays can be applied to all substation configurations and can monitor the switchgear positions of all connected plant.
Relays are housed in size E8, E12 or E16 cases. Integrated logic is provided to allow the optimal configuration of the relays analogue inputs and binary input/output circuits.
Protection, instrumentation and metering functionality is accessible via data comms channels. A 25 pin RS232 front port for local PC connection and two rear fibre optic ports for remote connection are provided.
