N2 - This paper presents a novel computer-based PD measurement system, which incorporates the conventional partial discharge detection circuits with a real-time oscilloscope of very wide bandwidth up to the order of gigahertz. The calibration pulse of the detection circuit is investigated for the denoising purposes. A sophisticated analytical tool, wavelet analysis, has been proposed and realised to preprocess PD data as acquired in the measuring system. On this basis, PD patterns during an adequate recording duration are given to further identify the origin of the PD source.
