  • Three Phase Transformer Ttr Meter Turns Ratio Tester - China

    price: contact company for price

    Item: RUN-HTT10F

    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.

    Advantage: Perfect and reliable automatic protection and built in battery

    Handheld TTR tester is more convenient and can be connected to Bluetooth.

    Parameters of Handheld Transformer turns ratio tester

    The Three phase Transformer Turns Ratio Tester ensures that the transformer windings have the proper turns to produce the voltages required.

    The ratio is a measure of the voltage applied to the primary terminals to the voltage measured at the secondary terminals.

    The following video of the transformer turns ratio tester is we taken in our transformer factory, hope it will be helpful for all of you.

    1 Test Range ratio 0.9~10000

    2 Accuracy ±0.1%+2 digit 0.9-500 ±0.2%+2 digit 501-2000 ±0.5%+2 digit 2001-10000

    3 Output Voltage Automatically adjust according to load

    Main features for TTR Meter

    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 wiring group 0-11 can be automatically identified.

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

    4 - With high and low voltage reverse connection protection, transformer turn-to-turn short-circuit protection, tap switch failure protection, output full short-circuit protection, and increase the stability of the instrument.

    5 - After inputting the rated parameters, it can automatically measure the transformer ratio, error value and tap position of the tap changer.

    Especially for tap changers with asymmetric tapping, the accurate position of the tap changer of the transformer can also be accurately measured.

    A tap switches capable of measuring 99 tap positions.

    6 - Adopt 7-inch high-definition color touch screen LCD, modular display, good visibility even under strong light.

    7 - Can be connected to an external printer to print measurement data, environment friendly.

    8 - High quality multifunctional engineering plastic box is cold-resistance, high temperature resistance, water proof, shake proof, which is suitable for field test.
