Wall-Mount Active Harmonic Filter - Cost Effective Power Quality Modules with PFC
Press release date: January 6, 2014
These active harmonic filters have ultra-fast (21µs) reactive power compensation, phase compensation current of 60A to 300A extendable and harmonic correction is provided for harmonics to the 50th order. Additional features include flicker compensation, ultra-fast response time of <300µs, load balancing between phases and unload neutral wire and grid resonance detection. Communication connections via Ethernet and Ethercat system, Ethernet TCP/IP interface permits control via browser. Subsystems display control unit, active sensor unit, ModBus, PQ Analyzer.
Harmonic currents generate power that cannot be used and consumes electrical system capacity. Large quantities of harmonics can lead to malfunctioning of the system that results in downtime and increase in operating costs. The PB-W Series active harmonic filter monitors the current signal and compensates for the unwanted elements of the measured current, thus eliminating harmonic oscillations and consequently costs savings for reactive energy.
