Application | Automatic Transformer Turns Ratio Tester (TTR Tester)

In the production process of semi-finished and finished power transformers, before the newly installed transformer is 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 the operating transformer, and the transformer turns ratio can be checked. The correctness, the condition of the tap changer, whether the transformer is short-circuited between turns, and whether the transformer can be operated in parallel.

The traditional turns ratio uses the turns ratio bridge to measure the turns ratio of the transformer. The operation process is cumbersome, the measurement range is narrow, and the readings are not intuitive. The bridge has to be converted and can only be measured phase by phase, which is no longer suitable for the requirements of fast and high efficiency modern measurement. Therefore, PureTech develops a new generation of HVBB automatic turns ratio tester (TTR tester) which adopts modern electronic technology.
The HVBB transformer ratio tester overcomes the shortcomings of the traditional turns ratio bridge test. The operation is simple and intuitive. It adopts a three-phase precision inverter power supply, which is fast and accurate. It has small size, light weight, high precision and good stability. It uses a large-screen display, menu operation, and a friendly interface. The turns ratio group can be tested at one time. This instrument is an ideal test instrument for the electric power industry sector.
