1. What is the working principle and function of high-voltage arrester?
High voltage arrester
The high-voltage arrester is connected between the wire and the ground and is connected in parallel with the protected equipment to protect the equipment from lightning strikes. The working principle of the high-voltage arrester is that when struck by lightning, the arrester discharges, introducing the lightning current into the earth through the conductor, and then using the grounding device to make the lightning voltage lower than the voltage that the protection equipment can withstand.
2. What is the difference between high-voltage arrester and low-voltage arrester?
The main difference is the open circuit voltage.
3. If a high-voltage arrester is installed on the power line, do I still need to install a low-voltage arrester?
Metal oxide arrester
It is necessary to consider the possibility of lightning strikes on the low-voltage side, and install it if possible. If the line is short and does not cross different lightning protection zones, you can directly take shielding measures and do not install a low-voltage arrester.
4. What tools can be used to measure the quality of high-voltage arresters?
The quality of high-voltage arresters can only be tested with the help of professional testing equipment.
European cable connector
5. Can high-voltage arresters be reused?
As long as the high-voltage arrester is regularly inspected and meets the requirements, it can be reused.
