The cause and the effect

Harmonic distortion is caused by equipment that is non-linear loads. These loads use current in a pulsing manner and at times feed harmonic currents back into the wiring. In non-linear loads, the current waveform is different from the applied voltage waveform. This causes them to produce the following:

  • Voltage distortions
  • Excessive currents on neutral wires
  • Overheating of motors
  • Microprocessor control problems
  • Unexplained computer crashes
