  • Segregated phase comparison system
    Patent number: 3963964
    Abstract: This disclosure relates to phase comparison relaying systems for a three phase power transmission line in which the current is measured at each end of each phase conductor. The phasor difference of the currents in a selected two of the phase conductors is determined at each end of the selected conductors and is phase compared to determine the location of phase-to-phase faults whether or not a ground fault is involved while the phasor sum of the current in all three of the phase conductors is determined at each end of the phase conductors and is phase compared to determine the location of phase-to-ground faults.
