Evaluation of Moisture Ageing Status of Cross‐Linked Polyethylene Insulation in Power Cables at Different Temperatures

High Voltage, EarlyView.
ABSTRACT Cross‐linked polyethylene (XLPE) cables play an important role in power systems to transport electrical energy, and moisture is one of the important predisposing factors for insulation failure in medium and high‐voltage cables. In this paper, a temperature‐moisture accelerated ageing experiment is designed, and a method for assessing the ...
