Causes of Low-Frequency Resonance in Distribution Boxes
Vari-able frequency drives (VFDs) for motors, DC power supplies for computers, elec-tronic ballasts for fluorescent lighting, and other non-linear loads can create harmonics. Abstract—This is a summary of three different classes of ferroresonance problems commonly encountered on distribution systems. Ferroresonance, or nonlinear resonance, is a rare type of resonance in electric circuits which occurs when a circuit containing a nonlinear inductance is fed from a source that has series capacitance, and the circuit is subjected to a disturbance such as opening of a switch.
