The fundamental frequency current magnitudes for Winding 1 phases A, B, and C,
neutral, and ground are shown. The current angle for Phase A is always set to 0° as
it is used as reference for all other currents, both measured and derived. The
maximum specified load and average phase current are also shown for the specified
winding.

All positive-, negative-, and zero- sequence component phase angles are
referenced to the Winding 1 Phase A current
The positive-sequence current magnitudes and phase values for Windings 1, 2, and
3 are shown here.
