30 Degree Phase Shift on Transformers
Posted 19 February 2012 - 02:54 AM
Can someone verify the statement below for me:
Any step-up or step-down transformer with delta-to-wye or wye-to-delta trasformer will introduce a 30 degree phase shift for positive sequence voltages and currents SUCH THAT THE HIGHER VOLTAGE SIDE LEAD THE CORRESPONDING VALUES ON THE LOWER SIDE.
In most of the information I found on the web; people in forums or documents I found, addressed only step down transformers.
Thanks in advance for your input

Delta-wye transformers always produce a phase shift, and can be connected for varying phase shifts in increments of 30 degrees, however they are typically connect for either +30 or -30 degrees.

I've run into a couple of these problems; however none of them indicate what the phase shift is. The solutions do seem to be consistent with the statement I posted.
