variable ratio tester

  • Transformer Ratio Tester-1

    In the production process of semi-finished and finished power transformers, before the newly installed transformers are put into operation, it is required to test the turn ratio or voltage ratio of the running transformers, so as to check the correctness of the turn ratio of transformers, the condition of tap changer, whether the transformers are short circuited between turns, and whether the transformers can operate in parallel. The traditional bridge reading is not intuitive, so the conversion can only be carried out phase by phase. RDB-Ⅲ transformer turn ratio tester overcomes the shortcomings of traditional ratio bridge test, which is easy to operate and intuitive. The TTR adopts three-phase precision inverter power supply, and has fast test and high accuracy
