摘　　要：在三相电能表检定装置的电流回路设置电流隔离互感器,可以实现三相电能表的不脱勾多表位等电位校验,也可检定内联式的三相电能表,是近年来推出的新型电能表检定装置,本文针对用于该种装置的电流隔离CT的测试方法进行了探讨,提出了使用标准互感器法和电能比较法两种方法,并对结果进行对比和分析。Setting up a current isolation transformer in the current loop of the three-phase energy meter testing device can make the three-phase energy meter not only realize the potential check such as not off the hook with multi-epitopes but also verify the inline three-phase energy meter. It is a new calibration device of electric energy meter which released in recent years. The paper investigated the current isolation CT testing methods used for this type of device and proposed two methods： Standard power transformer and Comparative Law. The results were compared and analyzed.
