Phase Shifts in Transformers:

What is the phase shift of secondary voltages and currents after converted to secondary voltage and current values based on turns ratio? Cant seem to find any infp. on this?

It is standard to always have the secondary side lag the primary side...
I thought the ANSI standard that is commonly applied in the US specifies the positive sequence voltage on the low voltage side lags the high voltage side. If you have a step down transformer, your terminology is correct, if it is a step up transformer, you would be incorrect.

I'm sure this phase shift can be modified for particular applications, but unless otherwise stated in a problem, what DK PE states above is correct.
