harmonic filters & capacitor banks - ECT Sales & Service

MEDIUM & HIGH VOLTAGE CAPACITORBANKSUNBALANCE RELAY•The individual fusing of the capacitors must be coordinatedwith the unbalance relay, in order to isolate a faulted capacitor,prior to trigger the hole bank out of service and giving a way tolocate the faulted capacitor.•The unbalance relay must have enough sensivity to give analarm when one unit fails and trigger the bank when variousunits fail, preventing an overvoltage of 110% rated voltage.
