This paper introduces the design principle of a partial discharge calibrator
and establishes a circuit model of the calibrator.Calculation with the model shows that the electric charge output of the calibrator is directly proportional to the voltage on resistance divider
and different charge output can be achieved by changing the dividing ratio of voltage.Experiment with the designed calibrator indicates that the charge output of the calibrator meets the index in the standard IEC 60270.
