    1.       LINEAR Load AC electrical loads where the voltage and current
      waveforms are sinusoidal. The current at any time is
      proportional to voltage. Linear Loads are:
      POWER FACTOR IMPROVEMENT CAPACITORS.             NON-LINEAR LOAD :
      AC electrical loads where the voltage and current
      waveforms are sinusoidal. The current at any time is
      proportional to voltage. Linear Loads are:
      POWER FACTOR IMPROVEMENT CAPACITORS,
      INDESCENT LAMPS, HEATERS ETC.
      Applies to those ac loads where the current is not
      propotional to the voltage. Foremost among loads
      meeting their definition are gas discharge lighting having
      saturated ballast coils and thyritor (SCR) controlled loads.
      The nature of non-linear loads is to generate harmonics
      in the current waveform. This distortion of the current
      waveform leads to distortion of the voltage waveform.
      Under these conditions, the voltage waveform is no
      longer proportional to the current. Non Linear Loads are :
      COMPUTER, LASER PRINTERS, SMPS, REACTIFIER, PLC,
      ELECTRONIC BALLAST, REFRIGERATOR, TV ETC.
