Partial discharge (PD) detection is an important means in the condition-based maintenance of high voltage apparatus including crosslinked polyethylene (XLPE) power cables. In this contribution, we introduce the recent work in Shanghai municipal electric power company on the condition-based maintenance of XLPE power cables. As to how to carry out the PD detection in different circumstances, three schemes are laid out in brief. Particularly, a novel idea of partial discharge joint detection method, which is based on multiple sensors, or the high frequency current transformer (HFCT) coupling technique, ultra high frequency (UHF) and acoustics emission (AE) partial discharge detection technique, is proposed. Use more than one kind of coupling techniques, the reliability of onsite PD detection and diagnosis can be improved significantly.
