Relay protection is an important measure to detect faults or abnormal situations in the power system, issue alarm signals, or directly isolate and cut off the faulty parts. Study power system faults and abnormal operating conditions that endanger safe operation, in order to explore anti accident automation measures for their countermeasures. Due to the fact that in its development, relays with contacts were mainly used to protect the power system and its components (generators, transformers, transmission lines, etc.) from damage, it is also known as relay protection. The basic task is to automatically remove the faulty equipment from the system or send signals to the on duty personnel to eliminate the root cause of abnormal working conditions in the shortest possible time and minimum area when there is a fault or abnormal working condition in the power system, in order to reduce or avoid equipment damage and the impact on adjacent area power supply
