摘要
文中通过对电流互感器的误差分析,得出误差与电流互感器铁心材料的磁性能有关,进而提出选用磁导率高的坡莫合金铁心材料设计电流互感器,经测试能达到0.1级测量精度。
Under the influence of the market competition,higher requirements on the accuracy of the current transformerfor metering was put forward.In this paper,the error of the current transformer was analyzed to find that the error was related to the magnetic properties of the core material of the current transformer,and then the choice of current transformer with permalloy core material with high magnetic permeability was proposed.The current transformer can reach 0.1 level of measurement accuracy.
