摘　　要：为改善电子式互感器的相位特性,提高其挂网运行稳定性,分析了电子式互感器中常用的模拟相位补偿技术,将模拟相位补偿技术与数字相位补偿技术进行了比较,分析了2种技术的优缺点,给出了二者的不同应用场合,提出了一种电子式互感器的数字相位补偿方法,在220 kV电子式互感器测量系统上进行了试验,补偿最小分辨率可至1′,补偿最大角度为270′,调节方便,可满足电子式互感器相位误差补偿的需求。This paper introduces the analog phase compensation technology used in electronic instrument transformer, puts forward a method of digital phase compensation in electronic instrument transformer and carries out in the measurement system of 220 kV electronic instrument transformers. The resolution ratio of the phase compensation is 1 second and the maximum range of the phase compensation is 270 second, which can meet the phase adjustment of electronic instrument transformers. It also compares differences between analog and digital phase compensation technologies, analyzes their characteristics and applications.
