Abstract
Current interrupters for high voltage networks are disclosed which sever the post-zero arc plasma, connecting a pair of arc terminating electrodes, near an upstream wall electrode and displace the severed plasma with a high dielectric strength gas, gaining dielectric strength faster than the transient network voltage recovers across the lengthening plasma discontinuity. Use of a high enthalpy dielectric displacement gas, created at the time of load or fault current interruption, makes plasma severing and displacement possible. High enthalpy displacement gas mixtures are preferably produced by combustion of solid propellants and/or ablation of solids rich in hydrogen.
