The paper presents the application of a new impedance relaying principle to a Teed feeder. The relay design is immune from false tripping owing to power swings or prefault load conditions. This has been achieved by extracting and using prefault and superimposed components of relaying voltages and currents. Results are presented for earth faults on a Teed feeder configuration. Relay trip time is typically in the range 11 to 20 ms and is plotted as a surface against prefault power angle and fault point on wave angle
