Research on Live Detection of Low Zero Value Insulators in Transmission Lines
Due to long-time load of the insulator in transmission lines,the insulation performance gradually decreases,so this paper proposes a method for the live detection of low zero value insulator in transmission lines.Firstly,the spatial electric field distribution of low zero value insulators is identified,the heat production law and common characteristics of low zero value insulators are obtained.Subsequently,the deteriorating low zero value insulators in transmission lines are detected to ensure the stability and reliability of electric power system.The experimental results show that,the live detection method of low zero value insulators in transmission lines can effectively detect the deteriorating insulators,and determine the judgment conditions according to the actual situation of each group of insulator strings,which greatly improves the accuracy of the deterioration of insulator strings.
