Charged Test Technical Of Capacitance Type Equipment

Validity analysis of charged testing method based on engineering application is studied in this thesis,and research on diagnosing equipment hidden trouble、stoppage, insulation defect in the test site. Measuring dielectric dissipation to the difference value and electric capacity ratio with relative comparison method,comparing two phase equipment with the current signal recordings of screen,it can eliminate impact of system operation mode and external environment factors to measure as much as possible. By means of test data analysis、partial discharge test、infrared measuring temperature、charged sample oil chromatographic analysis and collapse analysis to capacitance type equipment of substation, confirming test results correctness morely, finding hidden trouble,remove stoppage.By means of analyse to the scene charged test data long-term, establish processing standards to insulation problems of capacitance type equipment preliminarily.
