Abstrakt: Reports on the use of a method that produces a current zero point by superimposing a self-excited oscillatory current on a direct current arc. Coupling of an LC circuit in parallel to a SF[sub 6] gas circuit breaker; Generation of a large oscillatory current; Modified Mayr-type dynamic arc equation used.
