#7: Onsite Partial Discharge Testing on Power Transformers

Partial discharge (PD) measurements are a highly effective onsite diagnosis tool for the detection and localization of potential failure-causing insulation weak spots in power transformers. In this episode, OMICRON PD measurement experts Michael Krüger and Udo Ranninger describe the importance of onsite PD testing on both oil-filled and dry type power transformers, as well as how it is performed to effectively pinpoint insulation defects not revealed by other testing methods.
