摘要：The present invention comprises an antenna adapted to measure anelectromagnetic wave 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 TEMmode component from a measured time waveform; and a measurement device bodyincluding a processing section adapted to obtain a second order integral value of thetime waveform having undergone the filter processing and obtain a discharge chargequantity from the value. The present invention also comprises an electromagnetic waveradiation simulating apparatus for inputting a pseudo discharge signal to the device to bemeasured and previously obtaining the relation between the second order integral valueand the discharge charge quantity, wherein the processing section obtains the dischargecharge quantity from the second order integral value with reference to the previouslyobtained relation between the second order integral value and the discharge chargequantity.
