The basis for comparison between the various systems of power transmission is usually economy. If it is a 1-phase system, it includes two wires and when it is a 3-phase system, then it consists of either 3 wires (or) four wires. Rated voltage: 5V. I'm sure that a single-phase system derived with centre-tapped Neutral is definitely a 2-phase system, as each of the "outer" conductors operates in a different phase (shift 180 degrees).
