Power Quality (PQ) refers to the reliable delivery of electrical energy in a form that enables electrical equipment to operate properly. When dips and swells, spikes, surges, momentary outages, sags or other disturbances occur – computers and other electrically powered equipment may malfunction, fail prematurely or shut down unexpectedly

PQ improvement enables energy to be used more efficiently, optimizes the effectiveness of electrically-driven machines, equipment and systems, minimizes their wear-and-tear and increases their life cycle. Clean, uninterrupted power yields ecological and economic benefits. Higher output and greater reliability, less consumption
The quality of electrical power may be described as a set of values of parameters, such as:  
  Continuity of service
  Variation in voltage & frequency
  Transient voltages and currents
  Harmonic content in the waveforms


  Extends the life cycle
  Reduces power consumption on
  Produces sustained revenue increase
  Protects power grids
  Saves resources
  Optimizes production
  Produces sustained cost reduction
Telecommunication Center
Emergency generators produced sags and surges
Installed filters on generator control circuits
Mild shocks and flickering lights
Revised grounding connection
Repeated failure of critical care monitors
Installed transient voltage suppressors
Transfer switch mis-operation
Installed power factor correction Equipment
High Rise Building
Sporadic tripping of large circuit breaker
Replaced breaker trip unit with one less sensitive to harmonic current
Overheating and fuse blowing of PF correction capacitors, over heating of neutral conductors of supply transformers. Tripping of over current protection, mal-operations of relays
Installed passive and active harmonic filter
Data Center
Servers Failing
Overload neutral provided high neutral to ground voltage, possible cause for server power supply failure. Installed dedicated circuit for servers.
