Our process plant makes use of large 400 VAC 3 phase UPS system which then supplies, DCS, instrument DBs for field devices, DCS servers and finally 400 VAC MCCs.
This is the first plant where I have come across such system, and we have had a few very bad plant outages because of UPS failure.
I would like to hear of any person who has similar installations wrt problems, solutions, general opinion of UPS?
<b>Moderator's Note:</b> wrt is text speak for "with respect to." Had to look that one up.
