Motor frequency withstand voltage tester

PVT-20kVMotor frequency withstand voltage testerProduct Description

1. The high-voltage tester uses an electric voltage regulator to infinitely adjust the primary input voltage of the high-voltage test transformer, thereby changing the overall high-voltage output of the machine;

2. Before the experiment, the withstand voltage value, leakage current alarm value, and test duration can be set according to the requirements of the test sample;

3. After the boost start, the test voltage is increased to the rated test value at a certain rate;

4. The digital meter displays the test time, test voltage value, and leakage current value;

5. If the leakage current of the test sample exceeds the set value, the voltage tester will automatically alarm and cut off the high voltage, and the electric voltage regulator will automatically reduce the voltage to zero;

6. During the experiment, it has an audible and visual alarm function when the insulation of the test sample breaks down;

7. The instrument is equipped with a discharge button, which can release the residual voltage of the tested product and protect the personal safety of the operator;

8. Equipped with warning lights for high voltage warning and mushroom shaped emergency buttons;

9. Capable of printing and outputting;

10. After the experiment is completed, the electric voltage regulator continues to reduce the voltage to zero at the same rate as when the voltage was increased;

11. The tester with a maximum test voltage of less than 10kV has the function of finding the fault point: when the insulation breakdown of the test object occurs during the test process, an audible and visual alarm appears and the breakdown is not detected. You can place the "manual/automatic" button in the "manual" position, then set the leakage current to the maximum allowable value of the instrument, and slowly increase the test voltage through the "boost" button until flickering is observed.
