Autonomous partial discharge (PD) identification is not only key to the success of, but also one of the major challenges in, PD based condition monitoring of cable systems. In industrial applications, two challenges restrict the implementation of autonomous PD identification. The first challenge is that interference signals are of different shapes and the frequency bandwidths of some interference signals are similar to that of PD signals. The second challenge is that, as PD signals originate from different sources, their characteristics also vary.
