Phase comparison Technique (PCT) is a type of protection by which the quantities are conveyed through communication channels rather than wired interconnections of the relay input devices and it detects both phase and ground faults simultaneously. The phase comparison relaying principle is a line of differential relaying that compares the phase angles of the current entering one terminal of a transmission line with the phase angles of the current entering all the remote terminals of the same line. During normal conditions or through faults the currents. Why are seal-in and 52a contacts used in the dc control scheme?
