Abstract
The electrical arc is an electrical hazard with the likelihood of occurrence, to a greater or lesser degree, in energized systems, thus becoming an electrical hazard. This phenomenon causes the release of a large amount of energy, and its thermal effects are quite expressive. From the quantification of this energy, individual protection strategies applicable to the worker who will intervene in this type of scenario are chosen. This paper exposes the definition of these strategies for a hypothetical situation of intervention in an overhead distribution grid with the occurrence of an electrical arc caused by a three- phase fault. This choice is made from the incident energy estimation, using the IEEE Std 1584-2018 method and, the use of NFPA 70E-2021 standard to direct the applicable individual protection strategies.
