DR-082 CKSJ-2.1/0.48 7% Series Reactor for Capacitor Bank Power Factor Correction
The DR-082 CKSJ-2.1/0.48 7% Series Reactor is a high-performance inductive component specifically designed for capacitor bank power factor correction (PFC) systems. Engineered to work seamlessly with low-voltage reactive power compensation cabinets, it plays a critical role in enhancing power quality, protecting capacitors, and ensuring stable grid operation.
Harmonic Suppression
With a rated reactance rate of 7%, this series reactor is optimally tuned to suppress 5th and 7th harmonics—common in industrial grids with nonlinear loads such as rectifiers and converters. By connecting in series with capacitor banks, it effectively shifts the resonant frequency away from common harmonic ranges, preventing harmonic amplification that could damage capacitors and other critical electrical equipment.
