Note: Utilities bill reactive energy (kVArh) under different tariff structures — some penalize above a threshold (e.g., tan φ > 0.33), others bill per kVArh. Always confirm your utility's rule. In networks with harmonics (VFDs, UPS, LED drivers), fixed capacitors can resonate; use detuned reactors (typically 7% or 14% tuned) to avoid capacitor overloading and harmonic amplification.
Why this matters
Low power factor means you pull more current than needed for the same real work — increasing cable losses, transformer loading, and utility penalties. Correcting to 0.95 typically cuts reactive current by 20%+, freeing capacity and avoiding monthly kVArh charges. Get matched with suppliers on TUNA to source capacitor banks and detuned reactors at competitive rates.
