Questions
Common questions.
- What rating do you build APFC panels to?
- Up to 500 kVAR, in a compartmentalised modular design, with contactor or thyristor switching.
- How does an APFC panel save money?
- It corrects the plant power factor towards the target value, which reduces reactive power demand and the associated penalty on the electricity bill.
- Do I need detuned reactors?
- Where the supply carries significant harmonics, yes. We select detuned reactor and capacitor combinations to suit the power system rather than fitting capacitors alone.
- What happens when the plant runs on DG supply?
- The panel disconnects capacitor steps automatically during DG feeding, which protects the generator from leading power factor.
