AccuSine Power Correction System
Active harmonic filter to cancel harmonic content with dynamic injection of opposing current.
Power electronic devices which have repaid and frequent load variations have become abundant today due to their many process control related and energy saving benefits. However, they also bring couple major drawbacks in electrical distribution system; harmonics and rapid change of reactive power requirement. Harmonics may disrupt normal operation of other devices and increase operating costs. Rapid reactive power requirement change demands timely var compensation.
Symptoms of problematic harmonic levels include overheating of motors, drives, cables, thermal tripping of protective devices and logic faults of digital devices. In addition the life span of many devices can be reduced by elevated operating temperature caused by excessive voltage distortion.
The AccuSine® PCS Active Harmonic Filter (AHF) provides one of the simplest and most effective means to abate harmonics, reduce process related voltage fluctuations and improve equipment operating life.
