Power Harmonics Online Calculator



App description

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.

Electric arc heating equipment: such as electric arc furnace, electric welding machine, etc.

AC rectification of DC electrical equipment: such as electric locomotive, electrolysis, electroplating, etc.

AC rectifier and then inverter electrical equipment: such as frequency control, frequency conversion air conditioning, etc.

Switching power supply equipment: such as medium frequency furnace, color TV, computer, electronic rectifier, etc.

Usage example

Basic frequency : 200
