Product Features
    1. You can achieve the error test of capacitive PT (CVT), electromagnetic PT by using a single instrument , without resonance booster, standard voltage transformer, load box, tester and other equipment, greatly reducing the workload of the on-site check error.
    2. The test range is wide, can test the voltage level is 6kV~800kV electromagnetic voltage transformer.
    3. Using internal standard voltage transformer 0.01, low voltage transformer error measuring difference test; excitation characteristic curve can be obtained by using the frequency interval test technology, combined with the error of the measured value of low voltage transformer error range by extrapolation of the whole work. The test level of the instrument can reach level 0.05. During the test, the maximum output voltage is not more than 3kV, to ensure the safety of field testing.
    4. Bilingual comparison.
    5. The test wiring is simple, the operation is simple and easy to learn, only the operation of the transformer can be completed easily according to the operation of the guide prompt, and the testing efficiency is greatly improved.
    6. With the intelligent judgment of external wiring, wiring error, tip ratio, polarity errors etc..
    7. Automatic test data for the whole, and determine whether the ultra poor, poor data using the color display, the data characteristics of the transformer is simple and clear.
    8. Large memory can store the test data of up to 10000.
    9. Aluminum chassis, with good anti - interference, and to ensure the safety of the operator in the field of high pressure test and equipment safety.
    10. The use of high resolution, large size 8 inch true color LCD display, outdoor light with a clear display, with touch screen auxiliary operation, simple and quick.
