Journal Articles – High Voltage Laboratory | ETH Zurich switchgear using gas circuit breakers (CBs) in parallel to a LC-resonant path is used for decades already. This "passive oscillation" topology relies on negative damping of the oscillating current made possible by the fact that the voltage drop over the CB decreases with increasing current.

Introduction to Gas Insulated Substations / Switchgears (GIS) insulated switchgear parts. As the dielectric strength of SF6 gas is higher than air, the clearances required are smaller. Hence the overall size of each equipment and the complete sub-station is reduced. The various modules are factory assembled and are filled with SF6 gas. Thereafter, they are taken to site for final assembly.
