摘　　要：本文概述了3种时间同步方式秒脉冲、B码、IEEE1588的原理和特点,介绍了对电子式互感器进行误差校验时采用的同步脉冲法和固定延时法的特点。采用同步脉冲法,比较3种不同同步方式下的电子式互感器误差校验方法,得出并分析了误差数据和曲线比较图。结果表明IEEE1588同步方式能实现电子式互感器的误差现场校验,具有更广泛的应用。This paper outlines the technical principles and features of pulses per second（PPS）,Bcode and IEEE1588time synchronization protocols of three kinds of time synchronization modes,and introduces the characteristics of synchronized pulse method and fixed delay method on electronic transformer.Besides,the paper compares the error calibration methods of electronic transformer under three different means of synchronization,from which it arrives at and analyzes the error data and curve comparison chart.According to the results,the IEEE1588time synchronization method,with wider range of application,can be used in the on-site error calibration for electronic transformer.
