Arc Flash Protection Library for Assessment of Electrical Risk on Steel Manufacturer Users

This paper presents the results obtained from the simulation and development of an arc flash protection library for MATLAB/Simulink, including the models of the protection and grounding systems to study its influence on the incident energy. First, the background on the protection system, incident energy computation, and grounding systems is given in Section II. The background is used to present a series of examples on the incident energy computation and the selection of the parameters selected for the development of the arc flash protection library. Section III presents a methodology for the development proposed protection library. Section IV presents a case study on a local steel manufacturer user. Finally, conclusions and future work are shown.
