Lightning Arrester Features And Principle
Oct 08, 2018

The AC gapless metal oxide arrester has excellent nonlinear volt-ampere characteristics, good response characteristics, no freewheeling, large flow capacity, low residual voltage, strong overvoltage suppression, pollution resistance, anti-aging, and freedom from altitude. The structure is simple, no gap, strict sealing and long life.


The arrester exhibits a high resistance state under the normal system operating voltage, and only the micro-ampere current passes. It exhibits low resistance under the action of overvoltage and large current, which limits the residual voltage across the arrester.
