Power Factor
Instantaneous power is proportional to instantaneous voltage times instantaneous current. AC voltage causes the current to flow in a sine wave replicating the voltage wave. However, inductance in the motor windings somewhat delays current flow, resulting in a phase shift. This transmits less net power than perfectly timematched voltage and current of the same RMS values. Power factor is the fraction of power actually delivered in relation to the power that would be delivered by the same voltage and current without the phase shift. Low power factor does not imply lost or wasted power, just excess current. The energy associated with the excess current is alternately stored in the windings’ magnetic field and regenerated back to the line with each AC cycle. This exchange is called reactive power. Though reactive power is theoretically not lost, the distribution system must be sized to accommodate it, which is a cost factor. To reduce these costs, capacitors are used to “correct” low power factor. Capacitors can be thought of as electrical reservoirs to capture and reflect reactive power back to the motor.

RMS Voltage
AC voltage rises positive and falls negative 60 times per second, so how do you state its value? Industry practice is to quote the RMS voltage. RMS is a value 70.7% of the peak positive voltage. An RMS voltage will produce exactly the same heating rate in a resistive load as a DC voltage of the same value. RMS is the acronym for the mathematical steps used in its derivation. Square the voltage at all moments in an AC cycle, take the mean of these, and then take the square root of the mean. For reasons lost in obscurity, the steps are stated in reverse sequence, Root Mean Square.
Three-Phase Power Following the voltage, the power derived from an AC source peaks and falls to zero 120 times per second. This causes torque pulsations in motors, creating noise, vibration, and higher shaft stresses. Though minimal in fractional-horsepower household motors, this would be intolerable in larger motors. Larger motors usually require three-phase power, which avoids the problem. Three conductors supply AC voltage, offset in time or phase, so that they peak not simultaneously but at equally spaced intervals. This produces constant smooth torque from a motor, because at all moments, the sum of power from all three phases is constant. Three-phase power also eliminates the need for special starting windings required in single-phase motors.

Voltage Measurement
Voltage is a differential parameter; it is always measured between two points. There are two ways to measure three-phase voltage—between two of the three lines or between a line and neutral or ground. Service and motor voltages are quoted as line to line, unless otherwise noted. Because of the phase difference, line-to-line readings are 1.73 times line-to-neutral readings.
Inside a three-phase motor there are three windings, one for each phase. The easiest three-phase motor connection to visualize is with each of the three windings connected line to neutral. This is called wye because, schematically, it looks like the letter “Y”. A more common connection eliminates the neutral tie and connects the three windings from line to line. This is called delta because, schematically, this looks like a triangle or the Greek letter Delta. The winding experiences 73% higher voltage when connected line to line, so it must be designed for the type of connection it will have. Even if a motor’s windings are internally wye connected, its nameplate voltagerating is the line-to-line value
