Phase Rotation

Phase rotation defines the rotation in a Poly-Phase System and is generally stated as “1-2-3″, counterclockwise rotation. Utilities in the United States use “A-B-C” to define there respective phase names in place “1-2-3″. However some refer to there rotation as A-B-C, A-C-B, or C-B-A counterclockwise, were “A” can replace 1, 2, or 3. Europe adapted R-S-T to define the phase names.
