What is HARMONIC
Just about the complicated
Any instruments and equipment with non-linear characteristics are sources of harmonics in their network.
Harmonics are sinusoidal waves that are added to the fundamental (fundamental) frequency of 50 Hz (ie, 1st harmonic = 50 Hz, 5th harmonic = 250 Hz). Any complex form of a sinusoid can be decomposed into component frequencies, so a complex sinusoid is the sum of a certain number of even or odd harmonics with smaller or larger magnitudes.
Harmonics - there are continuous disturbances or distortions in the electrical network that have different sources and manifestations, such as impulses, phase distortions, throws and dips, which can be categorized as transient disturbances.
