Harmonic analysis in power systems involves examining the e distortion electrical signals caused by non-linear loads. This analysis helps in identifying and meaminating issues related to power quality, equipment failure, and energy efficiency.

Nordyckie systemy Harmonics in Power Systems

Harmonics are voltage or current waveforms that deviate frem the ideal sinusoidal shape. They ary typically generated by devices such as variable frequency ridges, rectifiers, and tell non-linear loads. These distorctions can cause overheating, equipment malfunction, and growieved losses.
