Power systems are designed to operate at frequencies of 50 or 60Hz. However, certain types of loads produce currents and voltages with frequencies that are integer multiples of the 50 or 60 Hz fundamental frequency. These higher frequencies are a form of electrical pollution known as power system harmonics. So, the harmonics current of order three would have a frequency of 150 hertz (3 X 50 hertz 150 hertz). Similarly, if we have harmonics of order 5, 7, and 9 then the harmonic frequency would be of 250 hertz, 350 hertz, and 450 hertz respectively.
