Low Voltage Power Factor Correction and Harmonic Filtering Equipment
- Low voltage power factor correction and harmonic filtering equipment
- Low voltage power factor correction and harmonic filtering equipment
- Reactive power compensation controller
Application
Low voltage power factor correction and harmonic filtering equipment is commonly applied to low voltage distribution systems, which is featured as low power factor, large harmonic current and unsteady load. This equipment can eliminate harmonics and improve power factor, which is widely applied to frequency conversion equipment, soft starter, uninterruptible power supply and other electrical equipment with large harmonic current and reactive load. The power factor correction and harmonic filtering equipment is commonly used in electric power, paper making, chemical industry, construction materials, textile industry and other fields.
