Abstract: At present, Chinese adjusted the national standards for transformers in accordance with the new international standard system. In order to help relevant technicians to better understand the differences between the national and international standards for electromagnetic voltage transformers, the technical differences between the GB/T 20840.3 standard and the IEC 61869-3 standard are explained, and the corresponding technical analysis is given. The reasons for the modification of each part are explained, and the impact of technical differences is interpreted, which can be used for reference by relevant technical personnel.
Key words: GB/T 20840.3; IEC 61869-3; standard differences; voltage transformer
