A harmonic-producing load can affect other loads if significant voltage distortion is caused. The voltage distortion is a function of both the system equivalent impedance and the amount of harmonics produced. Some of the main effects of voltage distortion are: control system interference, heating of rotating machines, overheating of capacitor banks, protection interference. Moreover problems could exponentially rise in case of resonance. Often the direct consequence of a harmonic analysis is the necessity to size a filter able to absorb the harmonics produced by distorting source.
