Abstract :
There are discussed the adequate problems to estimate the partial discharge (PD) behavior of typical PD arrangements under AC and DC conditions n the paper. The investigations were performed using typical PD test arrangements, corona, gliding and internal PD. For estimation of the PD behavior the standard phase resolved characteristics and PSA characteristics were used.
