Light Industries
Conventional manufacturing industries are adapting more and more non-linear loads in their electrical networks. Most of the industrial processes such as excursion, winding, compressors, pumps and fans are either fed with AC drives or DC drives. AC drives are built on 6-pulse diode rectifiers which create significant harmonic currents and distort the current sinewave. DC drives involve even more power quality problems, not only harmonic distortions but also low power factors. High harmonic currents in manufacturing plants increase energy losses in transformers and cables, contribute to the risk of breakdown of electronic cards and rapidly reduce the lifetime of plant equipment.
The key benefits of improving power quality in conventional manufacturing industries include:
