Scope
Main technical content: This document describes the rapid classification technology of pulse groups for intelligent detection of ultra-wideband partial discharges in power equipment, including pulse data acquisition and preprocessing, extraction of pulse waveform characteristic parameters, cluster analysis of pulse groups, and reconstruction and characterization of sub-pulse groups after classification. This document is applicable to diagnostic partial discharge tests using the pulse current method during withstand voltage tests, as well as to inspection-type partial discharge tests based on grounding conductors or pre-embedded coupling devices for live detection or online monitoring. Other partial discharge detection based on pulse waveform-time can be carried out in a similar manner.
