Power Quality Measurement

Power Linkers carries out Power Quality Measurement with 3 Phase Power Quality Meter. Fluke Model No 435-II Advance. The measurement is carried out with a very high accuracy instrument, i.e. Class A as per IEC 61000-4-30 std. The measurement is carried out as per IEEE 519-2014 standard.

  • The problems described below, reflects Poor Power Quality of Electrical System :
    1.     High THD and current Harmonic Content.
    2.     Voltage Sags and Swells.
    3.     Voltage Unbalance / Fluctuations.
    4.     Overheated Transformers and Motors.
    5.     Fuse switch over heating or flashing over.
    6.     PCB or Electronic card or component failure.
    7.     Lighting distribution system Neutral conductor burning out.
    8.     Power measurement errors.
    9.     Additional Power losses.
    10.   High neutral to ground voltages, resulting in failure of power supply units.
  • The Sources of Poor Power Quality / High Harmonics are :
    1.     Saturated Reactors
    2.     Thyristor-controlled motor drives.
    3.     Arc furnaces
    4.     Arc Welders
    5.     Induction furnaces
    6.     Gas-discharge lighting
    7.     Rectifiers
    8.     Electrolysis plants
    9.     Energy conservation devices, e.g. Soft Starters, Electronic Ballast & Fan Regulators
    10.   Equipment with SMPS e.g. TV receivers, PCs
    11.   CVTs
  • Causes :
    1.     Presence of "Harmonics" in Voltage, Current & Power.
    2.     "Sags & "Swells" in Voltage output.
    3.     Inrush current.
    4.     Unbalance Distribution.
