Optimized line reactor prevent nuisance tripping and reduce harmonic current. Power quality has degraded over time due to the increased use of non-linear loads. Low impedance, any application where a 3% reactor would be applied. Lowering injected percentage of harmonic current. Improving true power factor. Reducing cross-talk between drives. Adding impedance to drives with DC link chokes/reactors when more impedance is desired due to a relatively stiff source. Applications are oil and gas pumps, irrigation fields, farms, water, wastewater, HVAC, steel industry, Pulp/paper, machining, extruders.
