Abstract
Medium voltage cable characteristics have been determined with
respect to the parameters having influence on the evaluation of
results from PD-measurements on paper/oil and XLPE-cables. In
particular, parameters essential for discharge quantification and
location were measured. In order to relate a measured signal at
the cable terminations to a specific PD-amplitude and location on
the cable, the attenuation and the transmission speed of PD-pulses
on the cable have to be known. Consequently, the main parameter to
be determined is the complex propagation constant which consists
of the attenuation and phase constants. A method to estimate this
propagation constant, based on high frequency measurements, will
be presented and will be applied to different cable types under
different conditions. The influence of temperature and test
voltage was investigated. The relevance of the results for cable
diagnostics will be discussed.
