Understanding Arc Flash Boundaries: A Chart for Electrical Safety

Electrical safety is a critical concern in industrial settings, and one of the most significant risks is arc flash. According to CSA Z462 and NFPA-70E© 2015, workplace electrical safety standards, it's essential to perform arc flash hazard calculations to identify potential hazards and mitigate them. The Arc Flash Hazard Analysis module, integrated into CYME Power Engineering Software, helps achieve this goal by providing a comprehensive framework for assessing risk levels and adopting appropriate safety procedures.

The module uses robust short-circuit calculation algorithms to determine the short-circuit fault current and then combines it with time-current curves from its extensive device library to calculate clearing times. This information is used to compute incident energy and risk levels, allowing users to identify areas of high risk and take necessary precautions.

By utilizing the Arc Flash Hazard Analysis module, electrical professionals can evaluate the risk of arc flash hazards on any part of their network. This includes industrial, distribution, and transmission systems, ensuring a comprehensive approach to electrical safety.
