CHARACTERISTIC TESTING SYSTEM FOR PROTECTION RELAY DEVICE

摘要

Provided is a characteristic testing system for a protection relay device, and with the system it is possible to confirm the health of a test signal generated by a test-waveform generating circuit disposed in a relay protection device. The present invention includes a voltage measuring device (15) that measures a test signal from a test-waveform generating circuit (7) that generates a test signal which is input to a measurement circuit (6) and is from a processing signal from a computation processing unit (2) of a protection relay device (1).
