What are the precautions for using a zinc oxide lightning arrester tester?

1. Do not plug or unplug the measuring wire when inputting current and voltage to avoid damaging the zinc oxide lightning arrester tester.

2. Be sure not to reverse the input wires of the current signal and the voltage signal. If the input line of the current signal is connected to the measuring end of the testing transformer, it will inevitably cause equipment burnout and affect normal operation.

3. When PT obtains the reference voltage for the second time, the wiring should be carefully checked to prevent secondary short circuit accidents.

4. The zinc oxide lightning arrester tester should not be placed in a high temperature or humid environment to prevent moisture or damage.

5. If you find that the device is not working properly, you must first check the power fuse to see if there is any melting phenomenon. If equipment damage is found, please do not repair it yourself. Please contact the manufacturer of the zinc oxide lightning arrester tester in a timely manner Testing can only continue after replacing the same type of insurance.

6. During the connection process, the voltage and current sampling lines should not be reversed or connected incorrectly. During the test, the series excitation test transformer should not be used for high-voltage power supply; At the same time, it is necessary to prevent short circuits from occurring.

The zinc oxide lightning arrester tester is controlled by a microcontroller, which can display the true waveform of current and voltage, and the measurement results are very stable and accurate; Be sure to pay attention to the above points and every detail when using. Handle with caution to avoid accidents.
