Thanks for the paper, Bob. I've been looking for something similar for many of the Unit Sub locations at my work place. Now to get some of the systems engineers to accept it...

On another note, the IEEE needs to start included the publish date in their header for their papers.

This was a worthwhile read, and very pertintent to some work I am doing.
I know that Eng. Tips avoids commercial statements, and the paper was extremely good at saying who they bought the breaker from. I suspect there is more than one source, so maybe this would be the appropriate Q:
What companies make 15kV class breakers that can fit into a 15kV fuse compartment?
