This paper proposes a new integral methodology to overcome hidden failures and mitigates the electrical hazard due to arc-flash events during the protection of electrical systems. This methodology overcomes the drawbacks of present-day protective functions and their limitations. Also, considering the requirement to limit the maximum arc-flash hazard, a restriction has been implemented to coordinate the protection devices in the proposed methodology. The application results of the proposed methodology are shown on a steel manufacturer user showing the improvements by reducing the probably incident energy feasible due to arc-flash events.
