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 SIPROTEC 7SJ81 provides 4 low-power current transformer inputs and optionally 3 low-power voltage transformer inputs. With the same low-power current transformer (LPCT) a wide
The line differential protection SIPROTEC 7SD80 has been conceived for selective line protection of power cables and overhead lines up to 24km for all kind
