POWER FACTOR & APFC STUDY
Power Factor Improvement & APFC Panel Study
A low or unstable power factor may have more than one cause. We review operating load, capacitor-bank steps and switching behaviour before discussing correction.
What we review
- Existing and desired power factor
- Reactive-power requirement and capacitor-bank sizes
- APFC relay settings, step operation and contactor condition
- Relevant harmonics and operating-load variation
What you can expect
- Study findings and data-backed observations
- Approximate kVAR need where assumptions are sufficient
- Recommended further investigation or corrective action
Before we begin
These questions help us understand the site and propose a suitable scope.
- Is the PF consistently low or changing?
- Have capacitor steps failed or tripped?
- Is a recent electricity bill available?
Important scope note
Capacitor sizing is preliminary until harmonics, switching duty and operating conditions are considered.
