VFD line filter
VFD line filter
(OP)
Dear All
quite often we see installations of VFDs without the line harmonics filters (i do not mean the line chokes), concequently meading to failures to nearby capacitor banks installations.
What would be the recommended retrofit as regarding the input "cleaning"?

RE: VFD line filter
A generic recommendation when using VFD’s is to avoid power factor correction capacitive banks in the same power line.
RE: VFD line filter
Using power factor correction capacitor on same transformer as you have SCR and VFD drives is not recommended - at least not if the drive load is approaching about 20 percent of transformer capacity.
