How are the capacitive and inductive reactances of a power system affected by harmonics?
Capacitor are sensitive to the harmonics in the power system, whereas the capacitive reactance decreases with increase in the harmonic order increases
when inductor present in the power system , the inductive reactance increases with the increase in the harmonic order increases
to reduce the harmonics in the power system we install the capacitor power banks .
