Economics of Variable Frequency Drives for Irrigation Pumps June 23, 2016

Dilshad Brar, a graduate student in the UNL Biological Systems Engineering Department, looked at 1000 center pivot installations in 10 Nebraska counties to determine if placing a variable frequency drive (VFD) on the system would be economical. He also looked at the best location for the VFD pressure sensor. Brar breaks it down to four common scenarios, outlining when it pays and when it doesn't.
