Protection Relays

for Feeder Protection

Feeder protection ensures the uninterrupted operation of feeders, detecting faults and disturbances and avoiding their propagation to further parts of the electrical network.

Microelettrica solutions for Feeder protection are suitable to meet different needs, from overcurrent and earth-fault protection to additional voltage, frequency and directional discrimination functions, as well as specific standard compliances.
