Arrester Core
Arrester core is a type of electrical equipment used to protect electrical systems from damage due to lightning strikes or other forms of electrical surges. It consists of a metal core surrounded by an insulating material. The MOV core absorbs the energy of the surge, preventing it from damaging other components in the system. As a
How does an arrester core work?
Metal oxide varistors MOVs with a nonlinear resistance characteristic are frequently seen in an lightning arrester core. A voltage surge limits the voltage that is applied to the equipment because the MOVs become conductive and shunt the surge current away from it.
Can arrester cores prevent all voltage surges?
No, arrester cores cannot prevent all voltage surges, but they can limit the voltage applied to equipment and protect it from most surges. However, in some extreme cases, such as a direct lightning strike, the arrester core may not be able to protect the equipment.
