“…[6] The experimental study and field application show that the method can detect the UHF and ultrasonic signals of Partial discharge at the same time and compare and analyze the two kinds of signals, which can eliminate the field interference more effectively and realize the detection and location of GIS Partial discharge signals in operation. [7,8] In addition, Tuyet-Doan, V.-N combined the optical measurement method with UHF method, and proposed a GIS Partial discharge photoelectric joint diagnosis method, comprehensively using the information measured by the optical sensor and UHF sensor to identify the internal fault types of GIS, greatly improving the identification performance. [9] Mahdi, et al established GIS basin insulator PD simulation and multi-physical joint sensing system, and obtained the corresponding relationship between PD light pulse and pulse current signal under specific voltage.…”

Partial discharge of GIS equipment refers to various discharge phenomena caused by breakdown of local areas within the switching equipment. By monitoring GIS Partial discharge, insulation accidents can be effectively prevented. Currently, GIS equipment detection methods lack multi parameter information fusion state diagnosis methods for GIS equipment, and equipment state assessment techniques and operation and maintenance strategies based on GIS equipment multi basic parameters have not been formed. Setting up a simulation platform for the propagation characteristics of weak signals of electrical and optical state parameters inside GIS equipment, and mining the mathematical relationship between multi-source information and the type and deterioration degree of insulation defects inside GIS equipment by data analysis is helpful to evaluate the condition of GIS equipment, and then formulate reasonable operation and inspection strategies to ensure reliable operation of power grid.
