Arc-Flash Hazard Analysis and Mitigation Using SKM Power*Tools An arc-flash hazard analysis is an electrical engineering study: • To determine the risk of personnel injury as a result of exposure to incident energy released during an arc-flash event. • Provide recommendations for appropriate arc-flash hazard protection. • Inform the personnel about the existing arc flash hazard and evaluate ways to reduce it. • Comply with NEC 110.16, OSHA, NFPA 70E and IEEE 1584 standards. Based upon the results of an arc- flash hazard analysis, the rating of personal protective equipment (PPE) such as gloves, flame retardant shirts and pants, eye protection, etc can be properly selected for adequate personnel protection. Arc flash labels with this information will be provided as a part of this study. Protective Device Coordination Studies Coordination study are to: • Prevent injury to personnel • Minimize damage to system components • Limit the extent and duration of service interruption whenever equipment failure, human error, or adverse natural events occur on any portion of the electrical power system. • Produces time versus current coordination drawings with one-line diagrams and setting reports. • Avoid extensive plant outages and safety hazards to personnel and equipments. • Set the protective devices to trip in a desired sequence during the fault condition. • Isolate the problem area from the entire power system. • Ensure that all the equipments are adequately protected.
