What are the precautions for the use of zinc oxide arrester tester?

Zinc oxide Surge Arrester Tester is an instrument for testing the performance of zinc oxide arrester equipment. It can detect power failure or live state, and can timely find out whether the zinc oxide arrester is aging or damp. It has high measurement accuracy. The use and operation are simple and convenient, and have been widely used in many fields. Today, HV Hipot will give you a detailed introduction to the precautions for the use of the zinc oxide arrester tester.

1. Under the condition of input current and input voltage, be sure not to plug and unplug the measuring wire to prevent the zinc oxide arrester tester from being burned out.

2. Be sure not to connect the input line of the current signal and the input line of the voltage signal in reverse. If the input line of the current signal is connected to the measuring end of the test transformer, it will inevitably cause the equipment to burn out and affect the normal work.

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

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

5. If you find that the equipment works abnormally, you must first check the power supply insurance to see if it has a fuse phenomenon. If you find that the equipment is damaged, do not repair it yourself, and be sure to contact the manufacturer of the zinc oxide arrester tester in time. . The test can only be continued after the fuse of the same type has been replaced.

6. During the connection process, do not connect the voltage and current sampling lines in reverse or wrongly, and during the test, the series-excited test transformer cannot be used for the high-voltage power supply; at the same time, it is necessary to prevent short-circuits from occurring. .

The zinc oxide arrester tester is controlled by a single-chip microcomputer, which can display the real waveforms of current and voltage, and the measurement results are very stable and accurate; when you use it, you must pay attention to the above points, and pay attention to every detail. Operate carefully to avoid accidents.
