Abstract
A gas-filled surge arrester includes a pair of electrodes extending inwardly of an insulating spacer. The electrodes have end faces which are aligned oppositely within the insulator to define an arc or discharge gap therebetween. Each of the electrodes includes at least one cavity formed in the end face thereof adjacent and extending away from the discharge gap. The cavities are lined with a substance of relatively high electron emission ability.
