Power-quality equipment selection
Separate displacement power factor, distortion and supply events before choosing correction equipment.
Decisions before procurement
| Decision | What to establish | Evidence to bring |
|---|---|---|
| Plain capacitor bank | Review harmonics and source interaction first. Size reactive power from operating measurements. | kW, power factor and duty profile |
| Detuned bank | A series reactor changes resonance and capacitor duty. Selection needs a network study and matched components. | Spectrum, source impedance and stage configuration |
| Active filtering | Assess currents, neutral duty and operating modes to be compensated. Define performance at the connection point. | Measured distortion and acceptance criteria |
Your project brief
- kW, kvar, power factor and spectra
- Source data and existing bank ratings
- Load states and symptoms
- Connection point and performance target
Confirm the actual supply and control voltage. Kenyan projects commonly specify 230/240 V single-phase or 400/415 V three-phase; the selected equipment must match the measured supply and manufacturer rating.
