Abstract

The externally induced voltage identification measures the amplitude of the sum of the phase voltages or currents and the ampl amplitude of the difference between the iner-phase voltage or currents, and compres the amplitudes thus measured. For the inter-phase voltages or currents the inter-phase voltage or current are taken across one outermost phase and the central phase, and the inter-phase voltage or current across the central phase and the other outermost phase. The externally induced voltages are identified when the amplitude of the sum of the phase voltages or currents is one and a half times to two times greater than the predetermined.
