Abstract
Method and apparatus are provided for an emission controlled current limiting device. The apparatus may control the current thermionically, by cold cathode emission, by photo-emission, or with plasma devices; the common feature being that the current is limited by controlling a series emission process. The apparatus has applications in both power line transmission and distribution networks to protect existing utility equipment and reduce the cost of new equipment.
