ABSTRACT:
A gas filled surge arrester which has an extremely fast response to rapidly increasing surge voltages. A pair of electrodes define a discharge gap which is held in the range of 0.02 mm to 0.25 mm. A high electron emission ability substance partially fills a cavity in each electrode. At least a pair of conductors are associated with each electrode. The conductors define a discharge gap with the opposite electrode. The gap is held in the range of 0.02 mm to 0.30 mm. A gas made up of one or more of the noble gases and hydrogen fills the arrester. The hydrogen is held in the range of 0.1% to 20% of the total volume of the gas in the arrester.
