Ground distance relaying algorithm for high resistance fault
IET Generation, Transmission & Distribution, 2010 This study proposes a new fault impedance estimation algorithm of phase-ground fault for ground distance relaying based on the negative-, zero- and comprehensive negative-zero-sequence current component. The principle is based on the assumption that fault path is purely resistive, and the phase angle of fault point voltage and fault path current is ...
