Abstract

In order to understand the positioning and anti-interference technology of high-frequency partial discharge in transformers, a multi terminal coupled sensing technology for high-frequency partial discharge positioning and anti-interference in transformers has been proposed. This paper compares and analyzes the on-site application effects of different detection technologies, discusses the principles, influencing factors, and development trends of partial discharge joint detection and positioning technology, analyzes the shortcomings of traditional "electrical acoustic" joint positioning methods, and proposes the detection principles, steps, effects, and application scope of "ultra-high frequency ultrasonic" and "ultra-high frequency optical" joint positioning methods. It points out new research directions for faster and more accurate positioning of partial discharge live detection in on-site power equipment in the future.
