The inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but there is only one winding, which only hinders the change of current. If the inductor is in the state of no current passing through, when the circuit is connected It will try to hinder the flow of current through it. If the inductor...
Power Factor Correction Power Factor Correction improves the phase angle between the supply voltage and current while the real power consumption in watts remains the same, because as we have seen a pure reactance does not consume any real power. Adding an impedance in the form of capacitve reactance in parallel with the coil above will decrease Θ and thus increases the power f...
Effects of Harmonics : Increased losses Losses in capacitors The harmonic voltages applied to capacitors cause the flow of currents proportional to the frequency of the harmonics. These currents cause additional losses. Losses in conductors The active power transmitted to a load is a function of the fundamental component I1 of the current. When the current drawn by the load contains harmonics...
Why is the harmonic current on the null line mainly three times? This is due to two reasons: (1) Among the harmonic components generated by single-phase rectifier circuit, the third harmonic is the largest, and the distortion rate of the third harmonic usually reaches more than 80%. (2) The harmonic current of other times will have the effect of canceling on the zero line, onl...
