Primary Distribution Protection Relays – SIL RANGE

Primary Distribution Protection Relays – SIL RANGE

Relays of SIL family are designed to protect Primary and Secondary switching substations of electric distribution network.

One advantage over other equipments available on the market is that SIL relays facilitate the start-up of installations and the carrying out specific operations in adverse conditions.

The combination of the available IEC and ANSI curves and settings allows a precise combination with other equipments.

Our relays incorporate new industry trends as remote communication to facilitate the implementation of Smart Grid and Predictive Maintenance Network:
