Before any partial discharge test is conducted with high voltage applied, pulses of known charge values must be fed into the test circuit for calibration of the circuit and for determination of the scale factor of the PD measuring system. Various PD calibrators can be supplied for calibration of standardized PD measuring circuits according to IEC 60270, for RIV PD measurements, or for UHF PD measurements.
