Why did the high-voltage arrester suddenly explode?
Metal oxide arrester
During normal use, high-voltage arresters are often damaged, but some can be avoided. Therefore, when a large number of high-voltage arresters are damaged, the reasons should be analyzed to find out the reasons and avoid unnecessary losses.
Now I will introduce nine common causes of damage to high-voltage arresters:
1.Moist
Outdoor conditions are harsh and moisture is inevitable. Some measures can be taken to prevent moisture during installation
2. The rated voltage and continuous operating voltage are low
3. Grid voltage fluctuations
4. The problem of aging. Excessive use time causes the electronic components of the high-voltage arrester to age.

5.Harmonics
6. Poor impact resistance
7. Metal oxide high voltage arrester has poor overvoltage protection capability
8. Counterattack caused by unqualified grounding resistance
9. The high-voltage arrester is installed incorrectly
10. Incorrect selection of high-voltage arrester
