Abstract
This paper presents few case studies of condition assessment of extruded cables using very low frequency and spectroscopic techniques. Medium voltage distribution cables were assessed using VLF Techniques in addition to techniques like insulation resistance and spectroscopy. Few case studies of using low frequency partial discharge measurements for localisation of incipient faults are also presented and discussed. Studies indicate very low frequency tan δ and partial discharge techniques are promising tools for condition assessment of long length cables.
