At present, the FTU is debugged by connecting the FTU with a relay protection tester and simulating the field operation condition. However, the wiring process of the FTU and the relay protection tester is complex and tedious, so that the wiring time between the FTU and the relay protection tester is long and the accuracy is poor. Therefore, in order to solve the above problems, a wiring device of a relay protection tester and an FTU is provided.
