These diagrams show the current configuration and modes of operation for the power system. As the first step of the arc flash hazard analysis, accurate electrical system drawings are necessary to identify: power sources, voltage levels, electrical equipment (generators, transformers, motors, MCC’s, switchboards, panel boards, etc.) and protective devices (breakers, relays and fuses).
If your diagrams are accurate, send them to us and you are ready for the next step of your analysis. If your diagrams are NOT current, or do not exist, we can develop them for you. The duration of this process depends on the type and size of your facility and the quantity of equipment. We can use SKM System Analysis, Inc.TM Power Tools for Windows® software (preferred) or any other electrical engineering software that you require.
