SR2000B Automatic Three-Phase Transformer Turns Ratio Tester   During the production process of semi-finished and finished power transformers, before new transformers are put into operation, and according to the preventive test regulations of the Ministry of Electric Power, it is required to test the turns ratio or voltage ratio of operating transformers. This can check the correctness of the transformer turns ratio, the condition of the tap changer, whether the transformer has inter-turn short circuits, and whether transformers can operate in parallel. Traditional ratio bridges have non-intuitive readings, require conversion, and can only measure phase by phase. The SR2000B ratio tester overcomes the shortcomings of traditional ratio bridge testing. It is simple and intuitive to operate, completes three-phase ratio or turns ratio testing in one go, with fast testing and high accuracy.
