The HPS Centurion P Passive Harmonic Filter consists of reactors and capacitors in an LCL arrangement designed to reduce a broad range of harmonics associated with variable frequency drives and other three phase rectifiers. Hammond Power Solutions has added the HPS Centurion P Passive Harmonic Filter to its line of power quality products. It is specifically engineered to mitigate harmonic currents created by non-linear loads.
The initial product release from Hammond Power Solutions has ratings from 5 to 500 hp. It is said to improve power quality by simultaneously reducing harmonics and improving true power factor, resulting in an efficient and reliable solution.
The filter consists of reactors and capacitors in an LCL arrangement designed to reduce a broad range of harmonics associated with variable frequency drives and other three phase rectifiers.
The advanced design is said to deliver better performance compared to a traditional harmonic filter by reducing harmonic current distortion to less than 5%, corrects true power factor to over 95%, and meets IEEE 519 harmonic requirements.
Typical examples of passive harmonic filter applications include wastewater treatment plants, data centres, HVAC systems, material handling, mining, oil & gas, pulp & paper, and hospitals.
