Application of Time-Domain Electric Field Distribution in Switchgear Based on LOLA-Voronoi and Curvelet Transform

The purpose of this paper is to study the time-domain complex electric field distribution caused by partial discharge (PD) in switchgear, using LOLA-Voronoi adaptive sampling and compressed sensing technology based on curvelet transform. The possible discharge position in the switchgear is briefly described and the time-domain electric field distribution characteristics generated by the discharge at this position are analyzed, which provides a reference for the later research and optimization of the installation of UHF PD detection sensor in the switchgear.
