Performance of Reference Partial Discharge Measurement System

Electrical insulation problems emerge while decreasing energy losses by the use of high voltage. Several tests are carried out in the laboratory to determine the electrical insulation problems such as partial discharge (PD) test. Due to the requirement of high accuracy of PD test, the reference measurement systems with low uncertainty are needed. Standard PD measurement system consists of two parts, PD detector, and calibrator. The most important role of the precise PD measurements belongs to the calibrator. This paper presents here the performance of reference measuring system developed in TÜBİTAK UME for the calibration of PD calibrators.
