Study on Charge Standard for calibrating PD Measurement Equipments

Charge, Partial discharge

Plenary track > Calibration, Metrology and Standards

The characteristics of a portable charge standard for calibrating partial discharge(PD) measurement equipments are discussed and investigated in this paper. A portable PD calibrator and measuring system was set up by NIM, China. This calibrator and two typical commercial ones are measured by NIM’s digital system. The discharge impulses and the charge generated by the three calibrators are recorded and compared. The comparison results show that the portable PD calibrator is of good characteristic both in the range of charge and in the shape of its impulses and also in that of the repeatability.
