At the last ETAP Southern California User Group meeting on June 3, Albert Marroquin and Steve Chagolla kicked off the metting with a presentation on “How to Apply IEEE1584.1-2013 using ETAP”. The presentation focused on how to interpret the information provided in the “Guide for the specification of Scope and Deliverables Requirements for an Arc-Flash Hazard Calculation Study in Accordance with IEEE Std 1584™”.
Practical examples of analysis of simple and complex power systems were included in the presentation along with the options in the ETAP software which allow the formulation all the analysis scenarios suggested in the guide to find the worst-case results.
In depth explanation, of how to consider items such as “Main PD Isolation” or “Device Duty Evaluation prior to Arc-Flash Analysis” was provided.
The attendees benefitted by obtaining background information provided by the speaker on the formation of the guideline contents and gained deep understanding about the physical interpretation of the recommendations.
The presentation also covered arc flash study deliverables and learned how to easily generate reports
and label formats from the arc flash result analyzer tool in ETAP. Some label templates which are acceptable based on the latest revisions of NFPA 70E-2012 and the upcoming NFPA70E-2015 were provided.
