Improvements to PD measurements for factory and site acceptance tests of power transformers

The Technical Brochure (TB) of Joint Working Group JWG A2/D1.51 deals with possible improvements to partial discharge (PD) measurements for factory acceptance test (FAT) and site acceptance tests (SAT) of power transformers. In the joint working group, it is common understanding that a sensitive PD measurement is in the best interest of both, the transformer manufacturer, and the end user of power transformers. It ensures high quality, reduces the probability of failure and consequently lowers operational costs during the technical lifetime of transformers.
