摘要
针对电能表检定装置无法检定大电流钳形电流互感器误差的问题,介绍电能表现场校验仪中钳形电流互感器误差的实验室检定方法,并提出钳形电流互感器使用注意事项。
For handling the problem that large circuit chip-on ammeter errors occurs on ancient electric energy meter,this paper recommends test method of chip-on ammeter error on electric energy meter on-site test equipment,and presents the matters should be mentioned during application of the meter.
