At present, there are many types of microcomputer relay protection testers used in the field in China, and there are great differences in the performance, quality, structure and technology of the whole machine.

Although DLT624-1997 "Technical Conditions for Relay Protection Microcomputer Test Devices" puts forward clear requirements for relay protection microcomputer test devices, and stipulates regular inspection cycles and inspection items, but because there are no relevant inspection procedures or specifications, There is also no ready-made detection and analysis device, which brings certain difficulties to the acceptance and weekly inspection of the relay protection tester
