Fundamental insulation characteristics of air; N2, CO2, N2 ... 6 gas has excellent dielectric strength and interruption performance. For these reasons, it has been widely used for gas‐insulated switchgear (GIS). However, use of SF 6 gas has become regulated under agreements set at the 1997 COP3. Presently, development of a gas circuit breaker (GCB) using CO 2 gas and development of a high‐voltage vacuum circuit breaker (VCB) are being pursued.
