Harmonics are voltages or currents that operate at a frequency that is an integer (whole-number) multiple of the fundamental frequency. So given a 50Hz fundamental waveform, this means a 2nd harmonic frequency would be 100Hz (2 x 50Hz), a 3rd harmonic would be 150Hz (3 x 50Hz), a 5th at 250Hz, a 7th at 350Hz and so on. Harmonics in power systems result in increased heating in the equipment and conductors and create a pulsating torque in the motors. How to Calculate Harmonics.

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.
