Test transformer operation steps
And reliably ground the transformer and the control box; 1 Connect the leads according to the wiring schematic diagram.
Check whether the wiring of each part is in good contact, 2 before the test. And check whether the voltage regulator of the control box is adjusted to "zero" position;
The green indicator light is on, 3 Connect the power supply. Press the start button, the red indicator light is on, indicating that the transformer is energized, waiting for boost;
To increase pressure, 4 Turn the regulator handle clockwise at a constant speed. And pay close attention to the instrument instructions and the conditions of the test products;
The voltage should be quickly reduced to zero, 5 after the test. And press the stop button, then cut off the power and untie the test leads.
1 Environmental requirements for test transformers:
1.1 Input voltage: AC 220V or 380V 50Hz
1.2 Ambient temperature: -40 ℃ ~ 40 ℃;
1.3 Relative humidity: ≤ 85% when the ambient temperature is 25 ℃)
1.4 In an environment that does not contain chemical gases and steam;
1.5 In a gas without explosive hazard;
1.6 Under the place not subject to rain.
