Overcurrent protection – SIPROTEC 7SJ80
The SIPROTEC 7SJ80 relays can be used for feeder protection of high and medium-voltage networks with grounded, low-resistance grounded, isolated or a compensated neutral point. The relays have all the required functions to be applied as a backup relay to a transformer differential relay.
