Since the effective component of the AC grid is a single frequency of the power frequency, any component that is different from the power frequency can be called a harmonic. Since the sinusoidal voltage is pressurized to the non-linear load, the fundamental current is distorted to generate harmonics. The main non-linear loads are UPS, switching power supply, rectifier, inverter, inverter and so on.
The main contradiction affecting the quality of power grid voltage waveform is the non-linear electrical equipment, that is to say, the non-linear electrical equipment is the main harmonic source.
