when it boosts to a certain high voltage, press the button, the voltage drops to 75% of
the original value, and remains at this. This function is specially designed for zinc
oxide arrester to test the leakage current at 0.75U
DC-1mA
. After the test, automatically
reduce the voltage to zero and return to the test results.
7.LCD: 320X240 dot matrix LCD, displaying various setting parameters, test status,
results, prompts and other information.
8. Power input socket: connect with the power supply with the equipped power cable.
Power supply: AC 220V.
9. Air switch: control box switch.
10.Intermediate Frequency Output: Used for intermediate frequency connection
between control box and voltage boosting unit.
11.High voltage measurement: used for connecting the control box to the HV
boosting unit. The high voltage is input to the control box through a special three-core
cable. When connecting, simply point the red dot on the cable plug at the red dot on the
socket and turn it in place clockwise. Turn the cable plug in the opposite direction.
12. Rs-232 interface: used for online communication with computer.
13.Optical fiber microammeter: connect with high-voltage microammeter through
optical fiber.
14. Fan fuse.
15. Grounding terminal: this grounding terminal is connected to the voltage boosting
unit grounding terminal and test product grounding at one point and then connected to the
grounding grid. Please use the equiped ground cable.
