Protection Relays
for Transformer Protection
Transformers represent a fundamental part of Power Systems, which could be heavily affected by their downtime.
Microelettrica solutions protect Transformers from overloads, short circuits, and with differential protection functions ensure that 2-windings and 3-windings transformers are protected against internal fault that may occur, providing a timely trip of the circuit breaker.
