Abstract

This paper reports an expermintal investigation into the effect of different factors on the leakage current in power cables. The leakage current of different cables was studied using installed cables under actual operating conditions and also cable samples in HV-laboratory under well-controlled conditions.
The results obtained showed that, the leakage current in any power cable depends on many factors, including the value and type of the applied voltage, time of voltage application, cable type and construction, and the type of the surrounding soil and its resistivity. These results showed also that leakage current in power cables can be considered as a predictor of the cable failure because it is a good indicator of the cable deterioration.
