| Abstract: | 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. |
