NettetOne Line Diagram and Input Current Waveform A DC Link Choke will typically reduce current distortion by approximately 40 - 60%. This may or may not have a quantifiable impact on the measured voltage distortion. In the specification process, it is typical to substitute a DC Link Choke in place of a three phase input reactor. Nettet22. jun. 2024 · Line reactor as used in VFD/VSD application is an inductive component used in the line side or supply side for harmonics mitigation, voltage buffering, reduce commutation notches, reduction of differential mode noise etc. Line Reactors are specified based on the current rating (Amps) and the inductance (mH).

Nettet30. mar. 2024 · Calculating harmonics and measuring harmonics are critical steps in selecting the best harmonic solution to reduce the total harmonic distortion or THD on a power system to comply with the IEEE-519 standard.
