Ultra-high-speed schemes for the protection of long transmission lines

Abstract

It has been made clear in earlier chapters that unit-type protective schemes which compare the quantities at the two ends of transmission lines can provide the necessary discrimination between faults on the circuits they protect and both healthy conditions and faults on other circuits. Such schemes cannot however operate extremely rapidly because time must be allowed for the interchange of signals between the ends of the protected lines.
