ABSTRACT:
Disclosed herein is a three-element gas tube fail-safe station protector of known design modified to incorporate a back-up air gap system. To the ground terminal stud of the protector is added a lateral conductive member defining a pair of blade-shaped ground electrodes. To each of the line electrode terminal studs is added a conductive blade-shaped electrode which overlaps and is spaced from a respective one of the ground electrodes. The air gaps which are thus defined between ground and each line, i.e. paralleling the gas tube gaps, are encapsulated and dimensioned to provide back-up ionization in the event of a failure of the gas tube.
