I have an application where the location of about 20 of our well pumps (middle of aggie fields) will require us to run between 500' and 4100' from our VFD to our wells. The application really needs to be on a VFD, but reflected wave is a serious issue.
I have been recommended by a vendor to use a sine wave filter. This vendor claims to turn the pulse square wave into a fairly clean (5% to 7% harmonics) sine wave. To me it basically looks like an L-R-C filter without matching impedences to the specific application, but I am likely missing a few details. With these filters, they say there is no reflected wave and runs of 15,000 feet are possible.
Is anybody familiar with this technology? I have a few further questions, but mostly want to know if this is feasible.
Thanks.
