평등/불평등 전계하의 제조공기(I-Air)에 대한 압력별 절연파괴강도 특성

In this paper approves (AC and DC) high voltage by experimental GIS (Gas Insulated Switchgear) chamber and (AC and DC) power source to study breakdown characteristics by pressure(P) change and change of electrode distance(d) at (AC and DC) high voltage of Imitation Air(I-Air, N₂ : O₂ = 79[%] : 21[%]) to alternate SF? and achieved research. Gave P change of I-Air to study I-Air's Dielectric Strength using uniform and non-uniform fields(sphere-sphere and Needle-Plane electrode) and studied relations dielectric strength(V B ) by each P different d.
