Analysis of Defects and Countermeasures of Relay Protection Secondary Circuit
This paper expounds the defects in the secondary circuit of relay protection and proposes solutions to address them,including checking for disconnection faults in the secondary circuit,conducting insulation checks on the DC circuit,and selecting appropriate indicator lights to control the power supply,in order to reduce the probability of secondary circuit defects.
