Diagnosis of HV components by digital PD analyzer

摘要

This paper reports the development of a fingerprint technique to evaluate partial discharge (PD) measurements on HV components. Based on routine measurements in several actual HV objects, the recognition of different PD faults is discussed. The technique may help users identifying the cause of different types of insulation problems in HV equipment. More experience is still required to evaluate the effectiveness of this system on other independent samples.
