摘　　要：设计了一种高准确度的自补偿小电流互感器 ,对其线性度、比差与角差进行了测定 ,特别关注了 - 30℃～ +5 0℃范围内的温度特性和环境温度对互感器准确度的影响 。This paper designed a low current transformer with high accuracy and self compensation. The linearity, ratio difference and angle difference were also measured. Especially, the temperature characteristic of the transformer in the range from -30℃ to +50℃ was measured, and the influence of temperature on the precision of the transformer was analyzed. Finally, a method to correct the shift of errors was also presented here.
