発明の名称 (英語) PARTIAL DISCHARGE CHARGE QUANTITY MEASURING METHOD AND DEVICE 実績あり
発明の概要(英語) A partial discharge charge quantity measuring device comprises an antenna adapted for measuring a partial discharge radiated electromagnetic wave radiated from a device to be measured and having a sensitivity to at least the UHF band, a filter for extracting the TEM mode component from the measured time waveform, a measuring device body having a processing section for determining the second integral of the time waveform after the filtering and determining the discharge charge quantity from the second integral, and an electromagnetic radiation simulator for inputting a pseudo-discharge signal into the device to be measured and previously determining the relation between the second integral and the discharge charge quantity. The discharge charge quantity can be determined from the second integral by using the previously determined relation between the second integral and the discharge charge quantity by the processing section.
