Hi All,
Please educate me on line reactors.
VFD manuals suggest installing a line reactor between the AC supply line and the VFD when the supply has high fault current capacity.
I've always __assumed__ that this was just an inductor (per phase) to limit input current. (I'm working with single-phase power here.)
The descriptions on the Grainger website indicate that these have two windings. (These products are for three-phase applications.)
Anyhow, is this just a simple per-phase inductor, or something more complex?
And how does the "3%" spec relate to real inductance, as in Henries?
Thanks much.
