Zinc oxide arrester tester is an instrument to test the performance of zinc oxide lightning arrester. It can detect power failure or electrification status, and timely find out whether zinc oxide arrester is aged or affected with damp. It has been widely used in many fields because of its simple use, convenient operation and high measurement accuracy. Next, Kvtester will introduce the precautions for using the zinc oxide arrester tester in detail.
1. Under the condition of input current and input voltage, do not plug or unplug the measuring line to avoid burning out of the zinc oxide arrester tester.
2. Ensure that the current signal input line and voltage signal input line are not connected in reverse. If the input line of the current signal is connected to the measuring end of the test transformer, it will inevitably lead to the burning of the equipment and affect the normal operation.
3. When PT gets the reference voltage for the second time, carefully check the wiring to prevent secondary short circuit accident.
4. The zinc oxide arrester tester shall 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 fuse to see if it is fused. If you find that the equipment is damaged, please do not repair it by yourself, and make sure to contact the manufacturer of the zinc oxide arrester tester in a timely manner. The test can only be continued after the same type of fuse has been replaced.
6. During the connection, the voltage and current sampling lines shall not be connected in reverse or in error. During the test, the series excitation test transformer shall not be used for high-voltage power supply; At the same time, short circuits must be prevented.
The zinc oxide arrester tester is controlled by a single chip microcomputer, which can display the true waveform 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. Handle carefully to avoid accidents.
