Power Capacitors Overview
Self-healing power capacitors provide power factor correction by offsetting the reactive power drawn by motors, transformers, and other inductive loads. QDTB units use metallized film technology rated 0.40-1.0 kV from 1 kVar to 50 kVar at 50/60 Hz. The BSMJ series (PP film, oil-immersed) and BCMJ series self-heal on dielectric breakdown, improving safety and service life while reducing losses, improving efficiency, and avoiding utility power factor penalties.
