Does anyone have any experience with the calculations necessary to determine the DC arc fault incident energy levels that might be encountered while performing on line brush changes of a large utility synchronous generator?

Any information on this topic would be greatly appreciated.

A useful IEEE paper that I obtained previously in researching this subject:
" [SIZE=5][font=Courier][SIZE=3][font=arial]Paper Mill Case Study in Safety Improvements for Generator On-Line Brush[/font][/size][/font][/size][SIZE=5][font=Courier][SIZE=3][font=arial]Changing" Douglas Moody & Gary Custer, considers the protections, stored field energy and provides a hazard analysis. Collector ring barriers are also discussed in preventing short circuits.[/font][/size][/font][/size]

Thank you for the response, the paper is very informative.

where can I find that document?

thanks,
