摘　　要：针对时间同步方式对数字化变电站中电子式互感器校验的影响,阐述了一种基于IEEE1588同步对时方式的电子式互感器校验装置的设计方案和技术特点,分析了校验装置的误差来源,并对IEEE1588、秒脉冲、B码三种不同同步方式下电子式互感器误差校验进行了比较。结果表明,IEEE1588同步方式可满足电子式互感器的应用需求。According to the influence of clock synchronization mode on electronic transformer calibration in digital substation, this paper introduces the design scheme and technical features of a new calibration device of electronic trans- former based on IEEE1588 clock synchronization mode. And then the error source of the calibration device is analyzed. Finally, it compares the calibration errors of three clock synchronization modes including IEEE1588, 13 code and PPS. The results show that the IEEE5588 clock synchronization mode can meet the applied requirement of electronic transformer.
