The influence of water trees on permittivity and loss factor of medium voltage cables polyethylene insulation

This paper presents an experimental study regarding the variation of permittivity and loss factor of power cables polyethylene insulation, due to the change of the frequency (f a ) and the duration (τ) of the applied electrical field. The experiments were performed on XLPE flat disc samples from a m...
