Power factor correction
Motors and other inductive loads draw reactive power. A low power factor can trigger surcharges on commercial and industrial electricity bills and wastes capacity in your cables and transformer. Correctly sized capacitor banks fix this.
What the work includes
- Measurement of power factor and reactive load
- Capacitor bank sizing, including automatic stepped banks
- Harmonic assessment and detuned banks where needed
- Installation, commissioning and setting of controllers
- Inspection and repair of existing capacitor banks
When to call us
- Your bill shows a power factor surcharge or penalty
- An existing capacitor bank is faulty or disconnected
- Your transformer or main cables are running near capacity
- You have added drives or other non-linear loads
Common questions
How quickly does power factor correction pay back?
When a surcharge is being charged, payback is often fast. We calculate it from your actual bills before you commit.
Can capacitor banks cause problems?
Badly specified banks can resonate with harmonics. We assess harmonics first and specify detuned banks where needed.
