Abstract

This paper presents a new technique for locating partial discharges in HV cables. The method has been developed and used for on-line measurement of HV cable networks. When there is more than one PD site, the PD location procedure becomes intricate. The PD patterns are processed to detect the individual PD locations. An analogue model was built to verify and test the technique proposed. The results of the PD generated from the model are presented and discussed. Real data from the field are later compared to the results obtained from the model
