Power Qualty Cause The transmission of electricity from the power grid to the load side is mainly carried out using a three-phase line. Most of the industrial loads are also three-phase loads. The three-phase voltages produced in synchronous generators can be considered sinusoidal and symmetrical. The reason for the voltage and current distortion at a given point in the supply network is the wides...
Introduction In our modern world, the reliability and efficiency of electrical systems are more critical than ever. However, a common challenge that often goes unnoticed is harmonic distortion. This distortion can cause various problems, from decreased efficiency to equipment damage. To combat this, harmonic filters come into play. There are two main types: active harmonic filters (AHFs) and passi...
