摘要：

This paper deals with a new digital system for locating partial discharges (PD) in HV cables under noisy condition. After an introduction to different PD location methods and their limits, the possibility of PD location through pulse separation method is introduced. Subsequently digital filtering performed with predictor filters is described. Extensive investigations are carried out to determine the effectiveness of these filters, as well as their limitations, in their use for PD and noise separation. The paper ends with the introduction of the results concerning the application of filtering on PD and noise signals measured on a HV cable under noisy condition.
