摘　　要：为了保证电能计量的准确可靠,需对发供电企业现场运行的电压互感器和电流互感器进行现场校验,介绍了传统和电子式高压互感器现场使用标准互感器的比较法,并结合实际工作情况针对互感器现场校验过程中经常遇见的问题,如变比和极性错误,开路,信号未同步,无被检数据,误差超差等进行分析,提出相应的解决办法。In order to ensure the accuracy and reliability of electric energy metering,it is necessary to carry out on-site calibration of voltage transformers and current transformers in field operation of power generation and supply enterprises.This paper introduces the on-site calibration methods of various types of high-voltage transformers,and analyzes the problems often encountered in the on-site calibration process of transformers based on the actual working conditions,such as transformation ratio and polarity error,open circuit,signal non synchronization,no tested data,error out of tolerance,and puts forward the corresponding solutions.
