Handheld TTR Three Phase Transformer Turns Ratio Meter

Model: TTR-6810F (Bluetooth pinter is optional)

Ⅰ.Brief Introduction of Transformer Ratio Meter

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.

Functions: Checking the correctness of the transformer turns ratio, the condition of the tap changer, whether the transformer is short-circuited between turns, and whether the transformer can be operated in parallel.

It is especially suitable for special transformers such as Z-type transformers, rectifier transformers, etc.

Advantages: 7inch colorful touch screen, Perfect and reliable automatic protection and built in battery and USB interface. Handheld TTR tester is more convenient and can be connected to Bluetooth.

Ⅲ. Features and Advantages of Transformer TTR Measurement

(1).Using a three-phase precision inverter power supply as the measurement voltage, which eliminates the harmonic influence of the mains voltage during measurement and makes the measurement more accurate. no influence when working power source is generator.

(2).The three-phase output voltage is adopted to improve the test speed. The angle between phases can be measured, and the connection group 0-11 can be automatically identified.

(3).It is suitable for a wide variety of transformers, especially suitable for the measurement of Z-type transformers, rectifier transformers, grounding transformers, electric furnace transformers, phase-shifting transformers, etc.

(4).Multi protection functions: high and low voltage reverse connect protection, transformer inter-turns short circuit protection, tap-changer protection and output short circuit protection functions, increase the stability of instrument.

(5).After inputting the rated parameters, it can automatic measure transformer turns ratio, error and tap-changer position, especially for asymmetric tap-changer, the accurate position of the tap changer of the transformer can also be accurately measured. It can measure up to 99 tap positions.

(6).With High resolution 65K true color 7-inch touch screen, high brightness, and clear display even under strong light.

(7).Optional external Bluetooth printer for real-time data printing. Optional Bluetooth module.

(8).With sealed water-proof and shock-proof sturdy hand-case, suitable for field testing.
