Surge arrester is described by NEC as a protective device for limiting surge voltages by discharging or bypassing surge current on an electrical system to earth or ground. It also prevents continued flow of follow current while remaining capable of repeating these functions. In other words, a surge arrester’s purpose is to protect equipment or the system from damage due to transients.
