“…[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. [10] To sum up, researchers at home and abroad have accumulated some research experience in GIS Partial discharge multi-physical joint detection technology. However, most of the existing joint detection schemes are based on the combination of optical fiber sensing and ultra-high frequency method, and there is no relevant research report on the combination of optical measurement method, acoustic measurement method and ultra-high frequency method with higher accuracy.…”

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.
