ABSTRACT:
A voltage surge arrester disposed in a metal enclosure pipe containing an insulating gas is provided with a gas vent adjacent the line voltage terminal end of the arrester for venting gases which are generated inside the arrester. The vent is directed toward, and is in close proximity to, the inside surface of the metal housing. Upon failure of the arrester, the venting establishes a short circuit at the arrester line terminal, which both initiates the operation of a protective current interruption device elsewhere in the system and instantly diverts fault current from the arrester itself. As a result, fracturing of the porcelain, which would otherwise result from further pressure buildup in the arrester or from thermal shock, is avoided.
