  • A “LINEAR” LOAD CONNECTED TO AN ELECTRICAL POWER SYSTEM IS DEFINED AS A LOAD
    WHICH DRAWS CURRENT FROM SUPPLY WHICH IS PROPORTIONAL TO THE APPLIED VOLTAGE.
    FOR EXAMPLE: RESISTIVE LOAD, INCANDESCENT LOAD.
  • A LOAD IS CONSIDERED TO BE “NON-LINEAR”IF THE IMPEDANCE CHANGES WITH THE LOAD.
    DUE TO THIS CHANGE IN IMPEDANCE THE CURRENT DRAWN BY NON LINEAR LOAD IS
    ALSO NON SINUSOIDAL IN NATURE,EVEN WHEN IT IS CONNECTED TO SINUSOIDAL VOLTAGE SOURCE.
    FOR EXAMPLE: COMPUTERS, VARIABLE FREQUENCY DRIVES, DISCHARGE LIGHTNING.
  • THESE NON SINUSOIDAL CURRENT CONTAIN HARMONICS CURRENT WHICH INTERACTS WITH THE
    IMPEDANCE OF POWER DISTRIBUTION SYSTEM TO CREATE VOLTAGE DISTORTION THAT EFFECTS
    BOTH DISTRIBUTION SYSTEM EQUIPMENT AND THE LOAD CONNECTED TO IT.
  • STATIC POWER CONVERTERS ARE THE EQUIPMENT’S WHICH USE SEMICONDUCTORS TO
    CONVERT AC TO DC, DC TO AC AND AC TO AC AND CONSTITUTE LARGEST NON LINEAR LOAD
    CONNECTED TO ELECTRICAL POWER SYSTEM.
  • THESE CONVERTERS ARE USED IN VARIOUS PURPOSE IN INDUSTRY SUCH AS UNINTERRUPTED POWER SUPPLY,
    VARIABLE FREQUENCY DRIVES, SMPS ETC.THESE CONVERTORS USED IN VARIETY OF APPLICATION DRAW
    NON LINEAR CURRENT AND DISTORT THE SUPPLY VOLTAGE WAVEFORM.
  • THESE NON SINUSOIDAL COMPONENTS ARE DIVIDED INTO TWO COMPONENTS :
     FUNDAMENTAL COMPONENT AND HARMONICS COMPONENT.
  • THE HIGHER THE HARMONICS PORTION OF THE QUANTITY THE DISTORTION OF THIS QUANTITY OR IN
    OTHER WORDS THE LARGER THE DEVIATION OF THE QUANTITY FROM SINUSOIDAL FUNDAMENTAL FREQUENCY.
