Abstract :
The performance of phase-comparison pilot relays using fault superimposed components of current under different conditions is analyzed. The results show that phase-comparison pilot relays using fault superimposed positive sequence current or phase currents are more sensitive and reliable then traditional relays using composite sequence current or phase currents, and the relays based on fault superimposed current can overcome many drawbacks of traditional relays
