General information regarding partial discharge measurements on Power Electronic Capacitors

Hinweis: Diese Publikation liegt nur in englischer Sprache vor.

Statements regarding the lifetime of capacitors based on PD measurement results are not possible. Therefore partial discharge measurements parameters (voltage levels, waveforms and acceptancecriteria) as part of routine or type tests for Power Electronic Capacitors should be agreed between customer and capacitors manufacturers independently. An agreement is highly recommended in order to avoid overly complex designs which may not be technically necessary and could result in higher complexity and consumption of resources. A combined DC + AC test voltage is presented in this publication as a more practical approach for the typical application of DC Power Electronic Capacitors.
