In most cases, SCCAF (Short Circuit Coordination Arc Flash) studies are done by engineering firms, which then submit reports to facility owners. The challenge is that those reports tend to be lengthy (up to 5,000 pages), not engaging, and hard to grasp for facility personnel. ETAP's powerful graphical and presentation tools can help make those reports livelier, informative, and more engaging. This case study will discuss how you can summarize lengthy power studies reports within just a 30-minute interactive meeting, and highlight how the final ETAP model can be used, with its powerful graphical interface and presentation tools, including Data Blocks, Multiple Presentation layers, Sequence of Operations, and Arc flash calculator.
Multiple arc flash incident energy mitigation methods are available, but how does an engineer know which is best for their client? This presentation identifies an approach to follow to pick the method, considering effectiveness, practicality, feasibility, and overall best option for realistic study results. With extensive experience with arc flash studies for many clients of all sizes, Mangan provides a real world demonstration of a project for a refinery client. The interplay between motor starting and arc flash analysis was evaluated, and mitigation recommendations were customized for the system. The challenges encountered during mitigation are identified, and the proposed solution is analyzed using ETAP Load Flow, Short Circuit, Arc Flash and Motor Acceleration Analysis. Safe motor operation, safe motor starting and arc flash protection are provided through customized mitigation methods and thoughtful system design.
