The quantity of partial discharge is an important performance index of high voltage transformer.Excessive PD value will be harmful to the service time of the apparatus
and will cause potential danger.To avoid the fault of excessive PD
the factors causing excessive PD were analyzed.It was found that the reason of excessive PD resulting from the parts made of eligible insulation materials is difficult to detect and easy to be neglected.A case was given to describe the concerned analysis and detection methods.
