Abstract：The partial discharge apparent charge is a key parameter for the calibration and measurement capability of the International Bureau of Weights and Measures in the field of electromagnetic measurement database. In the detection of the partial discharge of the high-voltage equipment, the entire high-voltage circuit needs to be calibrated with a partial discharge calibrator first. The value of charge is an important guarantee for the accuracy of partial discharge measurement.Through theoretical derivation and measurement circuit simulation, the effects of source internal resistance, connecting cable and integral resistance of partial discharge calibrator on integral waveform and measurement results are analyzed.Through modifying the integral coefficient of each gear of the measurement system, an automated measurement software is developed independently and the overall measurement system is traced to DC current and time parameters. The capability verification results show that the measurement system meets the requirements of the reference charge meter.
