The Simplicity of Installing Metal-Enclosed Harmonic Filter Systems Watch for yourself the ease and simplicity of installing a NEPSI medium-voltage, metal-enclosed, C-HP (C-High-Pass) harmonic filter. These systems, which are designed and applied across many industries (including mining concentrate plants, chemical, renewables, general industrial, oil and gas processing, and more), install in less time, require a fraction of the foot-print, and come fully integrated, tested, and ready for interconnection.
Arc Flash Hazard Mitigation NEPSI showcases ABB’s ultra-fast earthing switch (UFES) in its medium voltage metal-enclosed harmonic filter banks. The ABB UFES switch is just one of many ways that NEPSI mitigates arc flash hazards and associated equipment damage from internal arcing faults.
Transient Free Switching Technology A General overview and description of NEPSI's implementation of the ABB’s DS1 transient free switching technology, its operating principles and advantages when compared to alternate technologies.
