Abstract
A surge arrester has end terminals having circumferential ridges, which, in the event of failure of varistor elements of the surge arrester, are designed to relocate the resulting arc and direct it in a manner which reduces or minimizes damage to the surge arrester. Grooves lead from the inner surface of the terminals to the ridges, to facilitate arc relocation.
