Introduction Power quality is a general term used to describe the compatibility between connected equipment and its electrical supply. The supply system can be affected by changes to the frequency or amplitude of the voltage, the balance between phases on a three-phase system, and distortion levels of the original signals. The characteristics that are important and what can be tolerated by the con...
Managing Non-Linear Load Harmonics with Active Power Filters Introduction Non-linear loads are becoming a significant challenge in today’s electrical systems. These loads cause the current to be non-sinusoidal, even when connected to a sinusoidal voltage source. This non-sinusoidal current contains harmonic currents that interact with the power distribution system, leading to v...
