Abstract:
1. A device for diverting energy away from an arc flash occurring within an electrical power system, the device comprising: an insulative base, said insulative base comprising a first mating feature; an arc source configured to create a second arc flash; a plasma gun configured and disposed to inject plasma in proximity of said arc source in response to the arc flash; an arc containment device configured and disposed to house said arc source and said plasma gun, said arc containment device including an exhaust port comprising a second mating feature and configured to route exhaust gases out of said arc containment device in a first direction; and an exhaust duct configured to be operatively coupled in flow communication with said exhaust port, said exhaust duct comprising a substantially hollow tube including a first tube portion and a second tube portion; said first tube portion configured to be coupled in flow communication with said exhaust port; said second tube portion defining an exhaust vent and coupled in flow communication with said first tube portion to route the exhaust gases out of said arc containment device in a second direction; wherein said first mating feature and said second mating feature are disposed to cooperate to operatively prevent an undesired blow-by of exhaust.
