What is the impact of 'harmonic distortion' on electrical equipment connected to a ship's power grid?

Harmonic distortion on a ship's power grid, which refers to the presence of unwanted frequency components (harmonics) in the voltage and current waveforms, can have several detrimental effects on electrical equipment. Harmonics are integer multiples of the fundamental frequency (typically 50 or 60 Hz). Nonlinear loads, such as variable frequency drives (VFDs), electronic power supplies, and arc furnaces, generate these harmonics. One major impact is increased heating in....
