Abstract

In online single-sided partial discharge (PD) location
settings, PD reflection patterns are affected by all
components present in the cable circuit. This paper
describes the performance of electromagnetic time
reversal (EMTR) when interfering reflections contribute
to the transient waveforms emitted by the PD. The
analysed situation refers to a ring main unit (RMU) in
the medium voltage (MV) grid where PD recordings are
disturbed by signals reflected from the other cables
connected to the RMU, potentially affecting the PD
location accuracy. We show that the accuracy of EMTRbased location methods is unaffected by such effects.
