Power frequency withstand voltage test transformeroperating steps

1. Connect the leads according to the wiring schematic and reliably ground the transformer and control box;

2. Before the experiment, check whether the wiring of each part is in good contact and whether the voltage regulator of the control box is adjusted to the 'zero' position;

3. Connect the power supply, the green indicator light will turn on. Press the start button, and the red indicator light will turn on, indicating that the transformer has been powered on and is waiting for voltage to increase;

4. Rotate the regulator handle clockwise at a constant speed to increase the pressure, and pay close attention to the instrument indication and the condition of the test sample;

5. After the experiment is completed, the voltage should be quickly reduced to zero and the stop button should be pressed, then the power should be cut off and the test lead should be disconnected.
