Arc Flash Modeling Services
Arc Flash is an intense release of energy due to an arcing fault between phases or phase to ground in a an electrical system. This energy release includes light, heat shrapnel and pressure waves which can cause severe burns, hearing damage and even death. Some common causes or arch flash events are tools shorting phase conductors, breaks or gaps in insulation, dust and other impurities on the surface conductors and equipment failure.

- Designing an electrical system that is reliable and easy to maintain is essential for trouble free operation over the long term. Achieving selective coordination while maintaining manageable arc flash levels can be challenging because the two tasks often conflict. Proper selection and arrangement of equipment and overcurrent devices can often make the task easier by isolating the fault and reducing fault current in one enclosure or cubicle. In some cases, different sections of equipment may be rated at different hazard risk levels which allows for easier maintenance. In all cases, designing a system with components that can easily and conveniently be de-energized is a must. of measurable project goals
- Performing an arc flash analysis provides an excellent opportunity to update the documentation of your electrical system. All aspects of the system need to be surveyed and recorded during the process including device ratings, conductor sizes and lengths, and equipment specifications. This process of information gathering al-lows for easy verification and updating of the facility single line diagrams. An electronic arc flash model can then be created using the survey information and single line diagrams as a reference. Once the model is created, updating the arc flash study and equipment labels becomes an easy task.
- After performing an arc flash analysis, it may be desirable to reduce incident energy levels at certain pieces of equipment for worker safety and ease of maintenance. Reducing the fault clearing time of the upstream over-current device is the most effective way to reduce incident energy. This can be accomplished in a number of different ways; however system reliability and continuity of power to critical processes must be examined prior to making any adjustments to overcurrent devices.
Please contact us with any questions related to arc flash safety, NFPA 70E, electrical system documentation, or protective device coordination. We would be happy to discuss your current situation as it relates to these issues and work with you to design a safety program so that your facility can be as reliable as possible while keeping your employees safe.
