Utility companies generate three phase electric power, which consists of three sinusoidal voltages with phase angles of 0, 120, and 240 degrees., The AC generators described in most introductory textbooks are single phase generators, so physics students are not likely to learn much about three phase power.

Active power (MW) will flow from the system with the faster frequency and to the system with the lower. When frequencies are the same, the voltage phase angle is constant. No power will flow when the breaker is closed when the synchroscope reaches the “12 o’clock” position (the point when the two systems are exactly in phase).

Since there are two live conductors in the system, it is sometimes incorrectly referred to as "two phase". To avoid confusion with split-phase motor start applications, it is appropriate to call this power distribution system a . 3-wire, single-phase, mid-point neutral. system.

The laterals may be three-phase, two-phase (two phases of the three-phase feeder with a neutral), or single-phase (one phase from the single phase feeder and a neutral). The laterals are usually protected with fuses so that faulted laterals do not cause interruption at the feeder level. Standard secondary voltage levels are . 120/240 single phase

Determining Motor Input Power. The best way to determine motor power consumption is with a power meter. Power meters simultaneously measure the current, voltage and power factor and combine these measurements to determine power. For a three-phase motor, the power consumption is: Power (kW) = Average Current of 3 Phases (A) x Voltage (V) x
