Arc Flash Hazard in Distribution System with Distributed Generation

This work presents the arc flash hazard assessment in distribution system including Distributed Generations (DGs). The results demonstrate the impacts of DGs on the incident energy released from arc due to short circuits. The fault current contribution from DGs decreases the arcing time consequently decreases the incident energy. This situation causes the underestimated arc flash hazard. Finally, the circumstances and the parameters should be aware for arc flash assessments are discussed.
