Abstract This paper summarizes the difference and applicable conditions of three arc flash hazard calculation method. Next, it points out the potential loopholes of methods and put forward a hazard calculation process after verifying their reasonability according to Lee’s model and mechanism of arc flash. Then, an example is given to evaluate the arc flash hazard occurring in an electrical device and verify the feasibility of the calculation process.
