Information

Arrester, surge arrester.

1) An appliance used to protect electrical equipment from high transient overvoltage hazards and to limit freewheeling time and often limit freewheeling amplitude. This term encompasses any external clearance necessary to perform the normal functioning of the appliance at the time of installation, whether or not it is a component of the whole.

Note 1: The arrester is usually connected between the grid conductor and the ground wire, but sometimes it is connected next to the electrical winding or between the conductors.

Note 2: Lightning arresters are sometimes referred to as overvoltage protectors, surge dividers.

Excerpted from: "Electrical terminology arrester, low voltage surge protector and components", GB/T 2900.12-2008.

2) Arrester is another important device that is often used when communication cables are protected against lightning damage. The following describes the relevant knowledge of the arrester.
