Usage of Primary Current Injection Test Set

Usage of Primary Current Injection Test Set: 1. According to the debugging requirements, connect the current regulator and the test object, and connect the power supply.
2. Choose the position of the current conversion switch based on the required current of the test object. As the current transformer does not allow open circuits, the current conversion switch can only be turned to the "large" or "small" position and cannot be placed in the middle position.
3. Turn on the power, the green light will be on (if the green light is not on, turn the voltage regulator knob counterclockwise to zero until the green light is on), press the start button, the green light will turn off and the red light will turn on. Rotate the voltage regulator handle clockwise to increase the current to the desired value.
4. Turn the voltage regulator handle counterclockwise to the zero position, press the stop button, the red light will turn off and the green light will turn on, indicating the end of the test.
