Are there standard cable resistances when none are available?
Are there standard cable resistances when none are available?
(OP)
Good afternoon,
I regularly perform short circuit and arc flash studies and throughout the various plants that we analyze there is always one or two runs of cable that has no resistance information given in my known library of documents. I was wondering if there is an IEEE (or otherwise) standard for resistances of cables that have no manufacturer data?
Thanks for the help,
Tim
