Abstract :
Time domain analysis of partial discharges is being considered as a means of characterization. However, multiple signal paths due to the reflection and scattering of the partial discharge pulse in the vicinity of the source and the antenna can affect both its amplitude and phase contents. This paper investigates the problems encountered at the time of characterizing radiometric measurements using time domain parameters. It introduces the concept of multipath propagation to radiometric discharge analysis and shows its capability to affect signal interpretation.
