non-linear loads

Non-linear loads are electrical devices that draw current in a way that doesn’t follow a smooth, straight line pattern. Unlike simple appliances that use electricity evenly, non-linear loads—like computers, LED lights, and variable speed drives—insert irregular or distorted currents into the power system. This can cause fluctuations, generate extra electrical noise, and create harmonics, potentially affecting power quality and other connected equipment. Essentially, non-linear loads shape the flow of electricity in a complex way, which requires special considerations in electrical design and maintenance.
