PREDICTIVE MODELING OF DC ARC FLASH IN 125 VOLT SYSTEM

electrocution/shock and arc flash. Arc flash is a phenomenon that occurs when a system has sufficient electrical energy to ionize surrounding air during a fault, thereby generating an arc. These incidents produce significant amounts of heat; however, heat is not the only form of hazard presented by arc flash.

DC arc flash assessment modeling Electric Arc

DC arc flash duration. The energy released during an arc flash event is roughly proportional to the arc duration. The upstream protective device operation controls the arc flash duration. A fuse or properly maintained overcurrent protective device has a predictable time to open the circuit with a specific arc current value.
