Power Quality Solution
Three Key Aspects Of Power Quality
- Power Factor
- Harmonics
- Disturbances
Effects of Harmonic Distortion
Overheating and additional losses in Transformers, Motors, Cables and Capacitors, Interference with communication and control signals, Malfunctioning relays and Computer Controlled Equipment, Disconnection or Failure of Capacitor Banks, Increased Losses in Distribution Gear and Transformers, Uncontrolled triggering of power switches/ fuses, Over voltage.
Symptoms of Harmonic Distortion
Tripped Circuit Breakers, Failed Capacitors, Blown Fuses, Motor Winding Failures, Overheated Transformers, Misfiring / Breakdown of AC / DC drives, Insulation failures, Computer failures, Telephone interference
Solution
- Detuned Harmonic solution– Avoid Resonance, Increase life of Capacitor
- Passive Harmonic Solution – Active front End of VFD
- Active Harmonic Solution – Centralised harmonic solution at incomer
- Hybrid Harmonic Solution – Combination of above.
