Lightning Arrester Characteristic Tester for Moa Testing
1. Designed in strict accordance with safety standards
2. Impulse voltage can be set
3. Select the calibration current according to the range of the lightning arrester online monitoring device, and automatically calibrate
4. The output voltage is automatically cut off after the measurement is completed
5. 2 kinds of power supply methods: use lithium ion battery to supply power, and can be charged in use state at the same time. In the event of a power failure, it can automatically switch from AC power supply to battery power supply.
6. Complete protection function, special discharge circuit for internal energy storage capacitor after the test is completed.
