Abstract :
Two different PD measurement instruments could detect different PD values on the same test object even if the measurement conditions are identical. This result is due to the quasi integration error presents in classical PD measurement systems. In this paper the quasi integration error is investigated and two parameters are proposed to qualify the PD detection instrumentation. Moreover a new approach to instrument calibration is depicted
