The digitized Partial Discharge (PD) signal recorded at one cable end consists of a sequence of pulses whose separation time contains information on the relative location of the PD sites. However, noisy PD signals can lead to a large PD site estimation error. The most annoying noise encountered during PD measurements consists primarily of Amplitude Modulated (AM) radio signals. The performance and the resolution of the wide band PD detection system are critically affected by this noise. This paper describes an Adaptive Noise Mitigating System (ANMS) which is aimed at effectively reducing this noise.
