Transformer Class ONS/ONP/OFP
Transformer Class ONS/ONP/OFP
(OP)
Can someone please tell me what these stand for:
ONS, ONP OFP
They come from a Tosiba 10MVA XFMR nameplace confirming to American Standard C57.12-1965.
I did a google search and an IEEE search. I also looked in the T&D, as well as C57.12-1986 & 2006 to no avail.

Strange thou I can't find a reference....
RE: Transformer Class ONS/ONP/OFP
I'm guessing:
ONS = Oil, Natural, Static - (No fans, just natural convection)
ONP = Oil, Natual, Pumped- (No fans, but forced oil flow)
OFP = Oil, Fans, Pumped - (Fans and Forced Oil )
But guessing at acronyms can lead to problems.

ONS, Oil natural, self
ONP Oil natural, pumped
OFP Oil Fan, pumped
Yeah you are right, guessing can lead to problems, which is always why I like to have a reference doc.
On the high note, for something like I say we are right.
BTW, thanks guys for the feedback. Always appreciate it :)

All well... I wrote those assumptions down on the SLD, and finished the work.
