| An arc fault in medium voltage or low voltage switchgear is one of the most devastating fault types in power systems. Term 'arc flash explosion' is a good characterization of the fault type. It causes a serious burn hazard to personnel along with several other safety hazards. An arc fault may also lead to significant economic losses directly, by damaging the equipment and indirectly, through power supply outages and production process interruptions. Several methods have been introduced to prevent arc faults and mitigate their impacts. In this research a comprehensive overview of the methods has been given, starting from the design of equipment until the extinction of the fault arc. |
