Can you stack medium voltage bus support/standoff insulators and get the same voltage rating at the overall height compared to a single insulator at that height. i.e. if I use two 6" insulators instead of a single 12" insulator should the clearance be "derated" at all? Would the BIL be the same?
I've got an application where I have a dedicated substation breaker supplying a single XFMR(D-Y) with a switch on the primary, a secondary main, and a 400A NGR. I am looking to set the primary breaker ground overcurrent as sensitive as possible(thinking instantaneous 50G) without concern of...
Looking for information on synchronous motor exciters, specifically any books or white papers that review the output waveforms of various packages or anything with good information.
Based on the latest NFPA 70E and other latest references/guidelines are single phase panels in industrial facilities required to have arc flash labels?
