Transformer Nameplate Data
Transformer Nameplate Data
(OP)
On a 13200/22860Y x 277/554 single phase transformer, what is the significance of the 554 on the nameplate data? This unit as used on a three phase bank is 277/480 secondary. Any ideas?






RE: Transformer Nameplate Data
There are two 277 Volt secondary windings that may be internally connected in parallel or in series.
