摘要：The present invention includes an antenna for measuring an electromagneticwave radiated from a device to be measured stemming from partial discharge and having
sensitivity at least in the UHF band; a filter for extracting a TEM mode component from ameasured time waveform; and a measurement device body including a processing sectionadapted to obtain a second order integral value of the time waveform having undergonethe filter processing and obtain a discharge charge quantity from the value. The presentinvention also comprises an electromagnetic wave radiation simulating apparatus forinputting a pseudo discharge signal to the device to be measured and previously
obtaining the relation between the second order integral value and the discharge chargequantity, the processing section obtains the discharge charge quantity from the secondorder integral value with reference to the previously obtained relation between thesecond order integral value and the discharge charge quantity.
