Impact of System Impedance on Harmonics Produced by Variable Frequency Drives (VFDs)
Variable Frequency Drives (VFDs) are utilized in commercial and industrial facilities to improve motor efficiency and provide process flexibility. VFDs are nonlinear loads that inject harmonic currents into the power system, and result in harmonic voltages across the system impedance. This harmoni...
