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 .

Vampire Power: Wasted Standby Power in Home Electronics and Appliances. Watt: a standard unit of measurement for electricity. The wattage of devices provides a means of determining relative electrical consumption. The rate at which power is consumed by a device or unit (such as a building) is often expressed in kilowatt-hours. Kilowatt Hour (kWh)

Measuring the power use of an appliance and the time it is used can be used to calculate the total electrical energy consumed. Energy = Power X time (kWh = watts/1000 X hours) Watt meters provide a convenient way to measure power consumption. Power consumption can also be determined through the appliance rating stamped on the appliance.
