Comparison of measurement methods for partial discharge measurement in power cables

Nowadays there are many partial discharge (PD) measurement systems on the market. There are systems that measure according to the IEC60270 standard (conventional measurement) and systems that don’t, the so called ‘’unconventional measurement systems’’. For PD measurement in power cables, measurement according to the standard has some shortcomings. Therefore development of unconventional measurement systems have taken place. Because there is no standard for these unconventional measurement systems, different manufacturers have developed different systems that use sensors with different bandwidths. Measurement with different systems could lead to different PD measurement results. Comparability of measurement results of different systems is desired in order to obtain an unambiguous result from different measurement systems for PD activity in the cable. Therefore there are investigated methods that create the possibility to compare measurement results of different systems that are used for PD measurement in power cables.
