Based on the Wireless-Current Method for Measurement and Test Analysis of Oxide Arrester Potential Distribution

Abstract

A method of measuring the MOA potential distribution of the new method:Wireless-current method is presentedin this paper, and developed based on Wireless-currentmethod of MOA potential distribution measurement system was solved by using thetraditional method to measure optical fiber test in each measuring point signal acquisition isnot synchronized, to elicit fiber and many other issues are difficult. This system could beobtained simultaneously arrester each node potential distribution and the applied value of thetest voltage, to realize digital measurement, through the application of this system for 500 kVzinc oxide surge arrester potential distribution test, with the measurement results arecomparative analysis, verify the correctness and practicability of the method. Measurementsystem based on this method developed can be used as surge arresters potential distributiontype test tools, especially for difficult to elicit measurement of fiber such as GIS tank typearrester potential distribution measurement is more effective.
