Based on the transformer calibration device based on voltage regulator, voltage booster and series resonance, CVT capacitive voltage transformer transformation ratio tester is a new generation of innovative PT test instrument developed after widely listening to users' opinions, after a lot of market research and in-depth theoretical research. It is at the leading level in China and is a professional instrument for transformer test in the power industry.

Method / step

1. When using CVT capacitance voltage transformer transformation ratio tester, it is necessary to read the following safety precautions to avoid personal injury and prevent damage to this product or any other products connected with it. In order to avoid possible danger, CVT capacitance voltage transformer ratio tester can only be used in the specified range.

2. Safety precautions:

1. Only qualified technicians can carry out maintenance and operation.

2. As a safety measure, the instrument is equipped with a protective grounding terminal. Before the test, the grounding terminal on the side of the device should be reliably grounded.

3. Prevent falling: do not place the instrument on an unstable platform or table top to prevent the instrument from falling and damaging.

4. Use appropriate power cord: the power cord with 220 VAC, 50 / 60 Hz and bearing current of 10A or above should be used.

5. Ensure good heat dissipation: the fans and ventilation holes on the side of the instrument are set for ventilation and heat dissipation, do not block them.

6. Prevent short circuit: do not let any foreign matter fall into the cabinet to avoid short circuit.

7. Connect and disconnect correctly: do not connect or disconnect the test lead while the equipment is being tested.

8. Do not operate without the cover plate of the instrument: if the cover plate or panel has been removed, do not operate the product.

9. Use appropriate fuse: 12A fuse is used for this equipment.

10. Avoid contact with exposed circuit and live metal: do not touch exposed contacts and parts when the product is electrified.

11. Do not operate in case of suspicious fault: if it is suspected that the product is damaged, please check it by our maintenance personnel, and do not continue to operate.

12. Operating environment: do not operate in humid or explosive environment.

13. This instrument is a precision electronic instrument. Please pay attention to prevent high temperature environment such as hot sun exposure when using it outdoors, and do a good job of shielding the hot sun and ventilation to prevent the instrument from overheating or reducing the measurement accuracy.

14. Product transportation: when transporting, please lay sponge and other cushion protection outside the instrument to avoid vibration and turbulence damaging the instrument or reducing the accuracy of the instrument.
