What causes harmonics in electrical systems

Harmonics are the result of nonlinear loads that convert AC line voltage to DC. Harmonics flow into the electrical system because of nonlinear electronic switching devices, such as variable frequency drives (VFDs), computer power supplies and energy-efficient lighting.

What causes even harmonics in a power systems?

Even harmonics are usually caused by so called space harmonics rather than time harmonics; i.e. asymmetries in the spatial distributions of the stator windings (due to slot spacing, for instance) rather than due to distortions in the time varying waveform of the input voltage.

What is harmonics in an electrical system?

What are harmonics in electricity? Harmonics are currents or voltages with frequencies that are integer multiples of the fundamental power frequency, which in the U.S. is 60 Hertz. If the first fundamental frequency is 60 Hz, then the second is 120 Hz, and the third is 180 Hz.
