1.What is Harmonics? In power systems, the fundamental cause of harmonics is the presence of non-linear loads. When current flows through a load and does not maintain a linear relationship with the applied voltage, a non-sinusoidal current is formed, meaning harmonics are generated in the circuit. Harmonic frequencies are integer multiples of the fundamental frequency. As proven by the French math...
