Comparison of partial discharge (PD) calibrators from 0.1 pC to 10 nC

Metrologia
Main text High-voltage partial discharge (PD) tests require calibration of PD measurement systems using PD calibrators which provide known values of the apparent charge. A set of travelling reference calibrators was circulated among 14 participating laboratories and each laboratory reported apparent change and rise time measured using ...
