电流互感器10%误差曲线的计算

Using V-A Character Curve to Draws up 10% Error Curve of Current Transformer

对于运行单位,测量电流互感器的10%误差曲线较为困难,现场通常进行伏安特性试验,并利用它的伏安特性曲线进行10%误差校核。

It is difficult for operation staff to meter the 10 % error curve of current ＇transformer. It is the practice at site that V-A character is tested to check the 10 % error curve with reference to its V-A character curve.
