electronic surge arrester
1. An apparatus used to switch to ground high-energy surges, reducing transient energy to a level safe for secondary protectors; for example, silicon rectifiers (electrical devices that have a higher conductance for current flowing in one direction than for current flowing in the opposite direction), Zener diodes (types of diodes that permit electric current not only in the forward direction like a normal diode, but also in the reverse direction), etc.

A surge arrester is a protective device designed primarily for the connection between a conductor of an electrical system and ground to limit the magnitude of transient overvoltages on equipment. A lightning arrester is really a voltage-surge arrester.
