Internal arc is a phenomenon which can happen in switchgear assemblies. so i am looking for a technology by which we can control the damages which will happen during internal arc. there is also a report for this test IEC 61641.
Powell Electrical makes arc resistant switchgear, which is designed to contain the arc blast within respective cubicle. They basically build the switchgear like a vault, and redirect the arc blast through vents in the roof that will safely send it away from personnel.
