Abstract

Focusing on off-line electrical diagnostics this paper presents a technical approach, including acceptance criteria options, for in-situ field condition assessment of 
MV paper insulated lead covered (PILC) cable and HV/EHV self-contained fluid-filled (SCFF) cables. The proposed approach consists of a combination of off-line AC Hipot, partial discharge (PD) measurement and frequency domain dielectric spectroscopy. Case studies illustrate the successful practical application of this
technical approach for diagnostics and condition assessment, including replacement prioritization or ‘return to service’ decisions on critical cables.
