摘要：

Partial discharge (PD) measurements taken on-site are frequently affected by noise due to external disturbances. This paper describes a noise reduction method that: may be used to isolate the PDs from the noise. The basic principles of wavelet de-noising analysis are presented. The PDs are then processed to allow accurate location of the PD. This method of location will also be presented.
