So I'm doing a delta wye transformer simulation in simulink, and I need some
clarification about transformer voltages.
Here's a image from a youtube video
We have phase voltages on primary that are 4160 V, but we also have Voltage A to ground, B to ground and C to ground which is 2400 V.
And on the secondary side when we will look for a phase shift we are going to look for a to ground, b to ground, and a to ground voltages that are 480 V.
So my question is when we have a transformer (delta-wye) for example 220kV/110kV, so primary voltage is 220kV, but what voltage is it, voltage A to ground(VAG in video) or phase A (VAB)?
