Transformer Nameplate Data 1

[shoegoo]

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?

Secondary voltage; either 277 Volts or 554 Volts.
There are two 277 Volt secondary windings that may be internally connected in parallel or in series.
