During the production process of semi-finished and finished power transformers, before newly installed transformers are put into operation, and in accordance with the preventive test regulations of the Ministry of Electric Power of the People's Republic of China, transformers are required to undergo turns ratio or voltage ratio tests. The traditional ratio bridge is cumbersome to operate, the readings are not intuitive, and necessary conversions are required. During testing, it can only be conducted on a single phase, resulting in low working efficiency. This series of instruments overcomes the shortcomings of traditional ratio bridge testing. The...
