Abstract
In a non-contact discharge test performed in a poor electromagnetic noise environment, the energy of discharge is evaluated by detecting weak light emission and processing the intensity waveform of light emission of the discharge. A database is created by measuring the intensity waveform of light emission of discharge generated as a result of application of a voltage or current to a measurement object through use of a light emission measuring device, simultaneously measuring the current waveform of the discharge through use of a current measuring device, and storing in the database the relation between analysis data sets obtained through analysis of the waveforms on the basis of information of the voltage or current applied to the measurement object. The intensity waveform of the light emission of the discharge or spark generated from the measurement object is measured while an electromagnetic wave generated as a result of the discharge of the measurement object is used as a reference. The magnitude of the discharge is estimated as a value by comparing light emission data obtained through analysis of the intensity waveform with the data recorded in the database.
