电子式互感器的现场检测及误差调试

On-site Detection and Error Debugging of Electronic Transformer

电子式互感器是智能变电站的重要组成部分,但目前缺乏全面、高效的检测方案和统一标准。它的准确性将直接影响计量、继电保护和控制装置。因此,基于电子式互感器的通用结构和合并单元,分析了现场调试中整体检测和单体检测的优缺点,介绍了电子式互感器误差调试流程。

Electronic transformer is an important part of intelligent substation.However,there is currently a lack of comprehensive and efficient detection scheme and unified standards.Its accuracy will directly affect measurement,relay protection and control devices.Based on the general structure of electronic transformer and the importance of merging unit,this paper analyzes the advantages and disadvantages of overall detection and single detection in field debugging,and introduces the error debugging process of electronic transformer.
