METAL-ENCLOSED HARMONIC FILTER BANKS...
METAL-ENCLOSED HARMONIC FILTER BANKS...
NEPSI's Medium Voltage Metal-enclosed Harmonic Filter Banks are custom designed for application on industrial, commercial, and utility power systems that require medium voltage power factor correction, var and voltage support, and mitigation from harmonic resonance or harmonic distortion. The harmonic filter banks are configurable as fixed or automatic controlled with 1 or more stages at voltages from 2.4kV through 38kV (60kV BIL through 200kV BIL).Available filter types include C-High-Pass (damped filters), High-Pass, Notch (Band-Pass), double-tuned, and multi-tuned filters. NEPSI's filters find wide application in many different industries including wind, mining, paper, chemical, and petroleum.
The filter banks are designed and customized by NEPSI to meet site and system requirements and can be configured to include some or all protection, control, switching, disconnecting and grounding functions.Harmonic filter banks are designed for placement in outdoor or indoor substations and come fully assembled, tested, and ready for interconnection.
FEATURES AND BENEFITS
Medium Voltage Metal-enclosed Harmonic Filter Banks offer many features and benefits over traditional open air (stack-rack) filter banks. When all costs are considered, including engineering, integration, site preparation, installation, maintenance, and liability, the Metal-Enclosed Filter Bank Design is the favorable choice.The following table summarizes the many features and benefits of applying metal-enclosed filter banks to your system.
