ABSTRACT:
An improved hermetically sealed gas tube surge arrester includes at least a pair of gap electrodes separated by an insulating spacer to form an electrode gap and a separate trigger electrode disposed about the region of the electrode gap for increasing the electrical field intensity in the region of the electrode gap. Preconditioning means is provided to direct an impulse voltage surge to the trigger electrode, prior to being impressed across the gap electrodes, thereby to precondition the electrode gap to breakdown at a relatively low impulse breakdown voltage.
