If a sine wave starts 30 electrical degrees before another, what is it called?

Explanation:
Leading describes the situation. When one sine wave reaches the same point in its cycle earlier than another, it is ahead in phase by that amount. Starting 30 electrical degrees before means this wave is 30 degrees ahead, so it leads. The other wave lags by 30 degrees. The term phase angle is the amount of separation, but the specific relation here is that the wave is leading. A transformer isn’t relevant to this phase relationship.
