This paper deals with the application of frequency domain dielectric spectroscopy for the detection of water trees in XLPE cables. During the research, dielectric spectroscopy measurements have been carried out on cable samples with and without water trees while it was attempted to preserve many of the uncertainties present in the field. The experiments support the applicability of a high voltage test developed primarily at KTH in Sweden, which utilizes the nonlinearity of the dissipation… CONTINUE READING
