Lightning Arrester

A lightning arrester is a device employed to safeguard electrical equipment against lightning-induced overvoltage, restricting both the duration and amplitude of freewheeling. Typically, it's installed between the power grid conductor and the ground wire, and occasionally adjacent to electrical windings or between conductors.


The arrester instantly begins to function, flowing charges and limiting the overvoltage amplitude to protect the equipment's insulation when the overvoltage value reaches the designated operating voltage. It then promptly returns to its initial state when the voltage value returns to normal, ensuring the system's normal power supply. It is also referred to as an overvoltage limiter or protector.
