Abstract
Modern partial discharge calibrators often have their lowest range below 1 pC. However, traceable calibration services below 1 pC charges are not widely available, or their uncertainties are relatively high because of low signal levels. Application of charge-sensitive preamplifier for the calibration of partial discharge calibrators provides a promising solution. This new calibration method both improves signal level and integrates the partial discharge pulse. The characteristics of the preamplifier can be corrected using a software, but after that the partial discharge calibrator calibration results have good signal level and repeatability. Estimated uncertainty is below 2 % for 0.1 pC.
