基于霍尔原理的高精度电流互感器电流补偿新方法

提出了一种以实现高精度为目标的电流互感器误差电流补偿的新方法。这种方法是采用基于磁平衡原理的霍尔电流传感器，检测出电流互感器的误差电流并直接补偿到其二次负载中，以消除电流互感器的激磁电流产生的误差。实验结果表明这种方法不仅是可行的，而且具有补偿效果明显和带负载能力强等特点，为研制高精度的电流互感器提供了一条新的途径。

A Novel Method of Error Current Compensation of CurrentTransformers for High Accuracy Based on hall Effect

In this paper , a novel method error current compensation of current transformers for high accuracy is presented. The method adopts the Hall cur- rent transducer based on magnetomotive force balance to detect the error cur- rent of CT and compensate the secondary burden directly so as to eliminate the error of CT caused by it's exciting current. The test results for this method show that it is not only feasible , but also has a remarkable compensation effect and an ability to take more burden.It presents a new way to make high accura- cy CT.
