Harmonics are a serious problem

Power Quality in times of blackouts and brownouts.
Power Quality has become the
buzzword of entire industries. While definitions diverge, nobody disputes its
importance and the consequences of poor Power Quality. Often, electric utilities
end up in the line of fire of frustrated customers. However, many disturbances –
like electromagnetic interferences or harmonics – are not attributable to the
utility company, but to the user of the electric power supply and the nature of
the connected loads.
Creation of harmonic currents and voltages.
Modern consumers of power, such
as variable speed drives for motor controls, switch-mode power supplies in home
electronics, or ballasts in fluorescent lamps, significantly contribute to energy
saving and a more efficient use of electricity. However, the nature of their
operation causes a non-sinusoidal current to be drawn from the grid. This non-
sinusoidal current consists of the fundamental 50 or 60Hz wave and its integer
multiples, the harmonics.
Harmonic currents flow through system impedances, transformers, reactors etc.,
and cause harmonic voltages. As a result, the supply voltage of other consumers
connected to the same branch of the grid is distorted, raising questions about
equipment service life, function, and reliability.
