the general methods of eliminating ferromagnetic resonance are introduced
and its problems are analyzed.To get the three-phase voltages and zero sequence voltage
by means of measuring the phase currents and zero sequence current across an earthing capacitor bank is proposed.This bank can replace the voltage transformer’s function of monitoring the insulation status.With this method
the neutral point of PT is removed
and the ferromagnetic resonance of PT is eliminated radically.The application results of a substation
