Abstract

Partial discharges (PD) are universally considered as one of the most important diagnostic indicators for the condition assessment of electrical equipment. The basic characteristics of traditional PD measuring systems are described in the relevant standard IEC 60270. The transition from analogue to digital PD measuring systems has had a significant impact on the possibility to use the measurement for diagnostic purposes and, moreover, has allowed the development of various PD source separation and defect localisation techniques. The proposed paper describes the research and development of advanced partial discharge analysis techniques and algorithms, focusing on the development of a custom ultra wide band measuring system. The adopted digital signal processing algorithms and the measurement results obtained from laboratory tests are presented and discussed.
