Product Overview
The hand-held transformer ratio tester is used for measuring the turn ratio or voltage ratio of power transformers and voltage transformers, and can meet the requirements of transformer production, installation, operation, and preventive power test procedures. During the production process of semi-finished and finished products of power transformers, before the 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, it is required to conduct a turn ratio or voltage ratio test on the operating transformers, which can check the correctness of the transformer turn ratio, the condition of the tap changer, whether the transformers have inter turn short circuits, and whether the transformers can operate in parallel. The traditional conversion ratio bridge reading is not intuitive and can only be measured phase by phase for conversion. This transformer ratio tester overcomes the shortcomings of traditional transformer ratio bridge testing, and its operation is simple and intuitive. It uses a three-phase precision inverter power supply, which is fast in testing and high in accuracy.
