Harmonics are periodic, sinusoidal & integer multiples of fundamental frequency (*0 or *0Hz), current or voltage components, present in nonsinusoidal waveform.
It distorts pure sinusoidal waveform and turns it to a non-sinusoidal waveform.
Harmonics can only be measured by electronic measurement devices
 
Industrial and Commercial applications are making increasing use of  large numbers of PCs, Servers, UPSs, AC / DC drives, Rectifiers, Chargers, SMPS, Energy saving CFL lamps, etc. These sorts of equipment draw current which is non-sinusoidal in nature, which categorises them as non-linear types of load. These non-linear loads put extensive stress on electrical distribution systems as a result of the generation of harmonic currents.
