Analysis on Abnormal Problems of Discontinuous Frequent Occurrence for Relay Protection

The discontinuous frequent abnormal problems of relay protection is a difficult problem for operator and maintenance workers. A comprehensive analysis approach should be used with consideration of many factors, such as features of the abnormal phenomena, operation performance, actual connection of the circuit, system failure, operation mode, altitude of load, operation conditions and climate influence. Every alarm signal should be fully considered to judge the nature of the abnormal phenomena and distinguish it inside the device or outside circuit connected to the device. In this way the solution will be given finally.
