Can AF rated switchgear by SquareD or other swgr mfr be modeled in ETAP or SKM to where when the AF analysis is run a low IE shows up instead of a higher IE that would be seen with non-AF rated swgr?
Thank you for the prompt and experienced replies. Luckily, I have both ETAP and SKM licenses. I also have not heard of modeling AF-resistant switchgear that would result in a lower IE but, the client did not like the initial IE levels from the study and wanted a response. I am also familiar with "Maintenance-mode" settings and using optical sensors in SEL 751A relays but, this just provides faster tripping times. I will also reach out to the makers of ETAP and SKM to see if this type of modeling is available.
