Discussion on Current Transformer Magnetic Saturation Margin and its Experimental Device
摘要
Abstract
To solve the test problem of current transformer magnetic saturation margin , the feasibility of methods in“power transformer verification procedures ” recommended by JJG 1021 has been analyzed.The analysis results show that the load error curve extrapolation method will well solve the current transformer magnetic saturation margin test problem without affecting the dissemination way of JJG 2082 “power frequency current ratio meter verification system diagram” in the national metrological verification system tables.Finally, the key technical parameters of testing device have been proposed through the analysis on encertainty of measuring results , which will provide theoretical foundation for development of current transformer magnetic saturation margin testing equipment .关键词
