摘　　要：针对现有数字输出的电子式互感器采用传统电磁式互感器校准方法进行校准时出现的时间偏移和采样不同步等问题,设计了一种电子式互感器校准系统。所设计的校准系统可实现对具有模拟量输出和数字量输出的电子式互感器的校准。性能测试结果表明,该系统比值误差小于0.05%,相位误差小于2',可用于0.2和0.2 s准确度等级的电子式互感器的校准。Aimed at problems including the time migration and the asynchronous sampling during the calibration of electronic transformers with digital outputs by traditional electromagnetic electronic transformer calibration methods, an electronic transformer calibration system is designed. The designed calibration system can realize the calibration of electronic transformers with analog and digital outputs. Performance testing results show that the ratio error of the system is less than 0.05% and the phase error is less than 2', which can be used in the calibration of electronic transformers with 0.2 and 0.2 s accuracy classes.
