    High Frequency Dielectric Loss Volume Resistivity Tester

    High Frequency Dielectric Loss Volume Resistivity Tester

    The anti-interference pilot frequency dielectric loss tester is a high-precision instrument for testing the dielectric loss tangent and capacitance of various high-voltage power equipment in power plant, substation and other field or laboratory.
    The anti-interference dielectric loss tester instrument is an integrated structure with built-in dielectric loss test bridge, variable frequency voltage regulating power supply, step-up transformer and SF6 high stability standard capacitor. The test high-voltage source is generated by the inverter inside the instrument, which is used to test the tested object after boosting by the transformer. The frequency can be 45Hz, 55Hz, 55Hz, 65Hz, 47.5 or 52.5Hz. The digital notch technology avoids the interference of power frequency electric field on the test, and fundamentally solves the problem of accurate measurement under the interference of strong electric field. At the same time, Capacitance&Dissipation Factor Test Set is suitable for the situation of power supply detection by generator after all power failure.

  • Transformer Turn Ratio Tester

    Transformer Turn Ratio Tester

    In the production process of semi-finished and finished power transformers, before the newly installed transformers are put into operation and according to the preventive test regulations, it is required to test the turn ratio or voltage ratio of the running transformers, so as to check the correctness of the turn ratio of transformers, the condition of tap changer, whether the transformers are short circuited between turns, and whether the transformers can operate in parallel.
    The traditional bridge reading is not intuitive, so the conversion can only be carried out phase by phase. RDB- II transformer ratio tester overcomes the shortcomings of traditional ratio bridge test, which is easy to operate and intuitive. TTR tester adopts three-phase precision inverter power supply, and has fast test and high accuracy.
