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...

In power supply systems, power factor is a crucial indicator, directly reflecting the efficiency of electrical equipment. A higher power factor means that electrical equipment is fully utilized and operates more efficiently; conversely, a lower power factor means lower utilization, like a car with a powerful engine that fails to deliver its full potential due to various reasons, wasting energy. Po...
