Implication of Poor Power Quality

Some of the implications of power quality are:

  • Premature failure of Motors, Transformers, Capacitor banks and Rotating Machines.
  • Malfunction of Controllers and protective devices such as fuses and relays.
  • Unexpected power supply failures (breakers tripping, fuses blowing).
  • Overheating, Generation of noise and reduced life of capacitors, surge suppressors, rotating machines, Transformers, cables etc.
  • Increased energy losses leading to higher operating temperatures and consequent reduction in life of cables, Transformers, Rotating Machines.
Power Quality Survey & Analysis

  • Site survey using Portable PQ Analyzers conforming to IEC 61000-4-30 Class A Ed-3 with 1 microsecond resolution
  • Measurement of semi sub cycle and steady state voltage variations and waveform distortions.
  • Data Analysis using advanced data Analytics software.
  • Wave form signature analysis.
  • Power system simulation studies.
  • Preparation of detailed Power Quality report with recommendations to Mitigate Power Quality Problems
