Energy efficiency and harmonics in electric power systems
... A harmonic is a wave whose frequency is an integer multiple of the frequency of some fundamental wave. When present in an electric power system it is added to the reference wave and the resulting wave becomes a fluctuating signal and thus the quality of the electricity is disfigured. They are genera ...

History of electric power transmission
The history of the technology of moving electricity far from where it was generated dates from the late 19th century. This includes movement of electricity in bulk (formally referred to as ""transmission""), and the delivery of electricity (""distribution"") to individual customers. The distinction between the two terms did not exist in early years and were used interchangeably.
