摘要
随着电度表技术的发展，对电度表检定装置提出了新的要求。本文论述了隔离电压互感器在多表位电度表检定装置中所起的作用和连接方法，给出了隔离电压互感器的自检线路和误差测试方法。
With development of watt hour meter technique,a still higher demand is set on calibration equipment for watt hour meter.In this paper, the functions and the con-nection methods of the isolated voltage transformer inside multi-meter calibrator are dis-cussed,the self-calibrating eircuit of the isolated voltage transformer and error measure-ment are described.
