A practical explanation of how PFC reduces reactive power charges, improves efficiency and lowers your electricity costs.
In simple terms, power factor is a measure of how efficiently your electrical system uses the power supplied by the grid. Industrial sites with motors, compressors, welders or HVAC equipment often draw more power than they actually use. This wasted energy is known as reactive power, and the utility charges you for it.
Power Factor Correction (PFC) reduces this wasted energy by installing capacitors or automatic systems that balance the electrical load. The result is lower bills, fewer penalties and a more efficient network.
Below is a simplified representation of real power, reactive power and apparent power:
Power Factor = kW ÷ kVA. Improving power factor reduces the kVAr component, lowering your overall demand.
Simple capacitor banks used for steady loads such as pumps or fans.
Multi‑step systems that adjust to changing load conditions using contactors or thyristors.
Used where harmonics are present. Protects capacitors and prevents resonance issues.
Static VAr Generators (SVG) respond to load changes within milliseconds, ideal for rapidly varying loads. Where high harmonic distortion is present, Active Power Filters (APF) cancel harmonic currents in real time without the resonance risk of passive capacitor banks.
