A kilowatt-hour (unit symbol: kW⋅h or kW h; commonly written as kWh) is a unit of energy: one kilowatt of power for one hour. In terms of SI derived units with special names, it equals 3.6 megajoules (MJ). Kilowatt-hours are a common billing unit for electrical energy delivered to consumers by electric utilities. (Wikipedia).

Explanation of how kilowatt-hour meters work (electromechanical)
I take apart an electromechanical power meter and describe how it uses magnetic fields to measure power consumed. The voltage coil's numerous turns of wire already provide some phase shift -- the copper ring adds additional shift to bring the total up to 90 degrees.
