摘要（英）：

The invention discloses a relay protection tester testing device. The relay protection tester testing device can take a test on the property of a relay protection tester. The relay protection tester testing device comprises a voltage signal conditioning module, a current signal conditioning module, an access device (AD) synchronous converter, a phase-locked loop module and a control module. The input end of the AD synchronous converter is respectively connected with the output end of the voltage signal conditioning module and the output end of the current signal conditioning module. A signal input end of the phase-locked loop module is connected with the output end of the voltage signal conditioning module. The output end of the phase-locked loop module is connected with the clock input channel of the AD synchronous converter. The signal output channel of the control module is connected with the other signal output channel of the phase-locked loop module, and the control module is connected with the AD synchronous converter.
