Özet

Ultra-dilute SF6 + N-2 mixtures are subjected to crossed fields with the applied magnetic field orthogonal to the electric field in order to investigate critical magnetic field values for suppression of electron avalanche growth resulting in increased dielectric strength. Electron avalanche growth inhibition together with the related electron mean energy variation are reported in the binary mixtures subjected to the combined fields. Even if very small amount of greenhouse gas (SF6) is used, high dielectric strength can be achieved in the binary mixtures with 0.25%, 0.50% and 0.75% SF6 contents subjected to the evaluated combined fields.
