⚡ 3% vs 5% Impedance AC Line Reactors, Harmonic Traps (THDi Cut from 85% to 35%)

VFD AC Line Reactor & Passive Trap Calculator

Size 3% and 5% impedance AC line reactors and tuned passive harmonic filter traps on industrial variable frequency drives (VFD): calculate line current THDi reduction (cutting input distortion from 85% down to <35%), protect VFD input diodes from utility capacitor switching surges, reduce motor reflected wave peak voltages, and equipment margins.
