Abstract: The paper describes a quadrilateral distance relay based on the comparison of instantaneous values of input signals for the measurement of impedance. The relay principle and the measuring scheme, incorporating dualcomparison, a transactor matched to the protected system and built - in d.c. supply circuits, are described. Operation of the relay under adverse conditions is analysed. Results of the laboratory tests conducted to ascertain the relay performance on steady - state and transient conditions are presented. The relay has the merits of requiring very simple input circuits and a flexibility of adjusting the constituent characteristics (reactance and ohm) independently and shows a satisfactory performance overall.
