Precautions for use and maintenance of primary current injection tester

1. When not in use for a long time, use a 500V megohmmeter to check the insulation resistance of the main circuit to ground before use.

2. The input voltage should be based on the voltage values on the nameplate (-220V, -380V), with a difference of ± 10% and a frequency of 50Hz.

3. Current switches are not allowed to operate with load.

4. When operating, the handwheel should be rotated at a constant speed and slowly to avoid damaging the regulator.

5. Full load working time shall not exceed 5 minutes, continuous working time shall be less than 2.5 minutes, but the working cycle shall be greater than 10 minutes.

6. The booster housing has a grounding terminal. Good grounding should be ensured during use.
