Research on UHV GIS Bus Fault Location Method Based on Protection Action Behavior and Ultra-high Frequency Monitoring

Abstract

To study the GIS fault location method with no obvious fault characteristics, this paper firstly studies the propagation characteristics of electromagnetic waves in GIS equipment, and then proposes a fault location method and system of GIS equipment based on protection action behavior and ultra-high frequency online monitoring. Finally, the effectiveness of this method is verified by an UHV GIS fault example.
