Power Quality

"Your One stop solution for Power Quality"

The use of sophisticated electronics equipment like Computers, DC Drives, Variable Frequency Drives, Thyristorised Heater Controllers, UPS, Switch Mode Power Supplies etc is increasing day by day in the industry.

These are non-linear loads and are responsible for harmonics generation. They draw non-sinusoidal current from the mains as compared to the linear loads like Incandescent lamps, Heating loads and Induction motor loads. They pose a big challenge for power quality.

The influence of the harmonics is not known to many and so this is neglected for quite some time. But they are responsible for,

  • Overheating, burnout or generation of vibration and beat noise in capacitors, reactors, generators and transformers
  • Overheating of neutral lines in 3-phase, 4-wire systems
  • Responsible for malfunction of control circuits of rectifier controllers
  • Nuisance tripping of protection relays and circuit breakers
  • Disturbance in communication lines and audio equipment
  • Deteriorate the computer performance
  • Error in watt-hour meter

It is customer’s responsibility to maintaining current distortion within the acceptable levels (Std. IEEE-519), while the utility is responsible for limiting voltage distortion.
