Harmonic assessment
Measure representative operating states before deciding on correction, detuning or active filtering.
Decisions before procurement
| Decision | What to establish | Evidence to bring |
|---|---|---|
| Survey | Record voltage/current distortion, spectra, power factor and neutral loading across the duty cycle. | Measurement locations and nonlinear load inventory |
| Network interaction | Review transformer/source impedance, capacitor stages and utility/generator modes together. | Source data, bank ratings and switching states |
| Mitigation | Separate displacement power factor from distortion. A plain capacitor bank is not a universal harmonic remedy. | Measured spectrum and defined acceptance criteria |
Your project brief
- Power-quality records and measurement periods
- Transformer, generator and capacitor details
- Drive, UPS and nonlinear load schedules
- Trip, overheating or billing symptoms
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.
