In supply RYB are mentioned. But in transformers, why they
are mentioning XYZ?
Answer Posted / pillay
RYB, RST, UVW, AND XYZ IS used simply to differentiate
the various terminals.
In a transformer there are actually two sets of terminals
actually you can name them both as RYB but how are you going to
differentiate from the primary and the secondary. Now we use RYB
OR RST as the primary and the secondary as XYZ OR UVW.We use
the same reasoning whenever there are two options for example the
power connections to a soft starter or the connections in a
variable frequency drive.
