We prepared base model and now it is necessary to add arc flash related data and parameters. it is a reference point for comparison of results and providing recommendations.implementing recommendations can take some time even counted in years, depending on size of facility, so existing results will serve as a base. ![]() it allows installation owner to act fast and provide temporary solutions to prevent staff from arc flash if necessary.It is important to identify existing situation because : It is called existing or as built situation as it provides information’s about incident energies and arc flash boundaries of current situation without any improvements. This step ends first part of arc flash analysis. Perform arc flash analysis – existing situation
