Variable Frequency Drives (VFDs) have been and continue to be used in many applications within our water and wastewater treatment plants. Applied correctly and the simple VFD will extend the life of your aging infrastructure and even reduce energy cost. Properly selecting a VFD may not be fully understood and this presentation will help demystify VFDs, providing a better understanding as to where and why you would use them. Attendees will cover:

•             The “Don’ts” such as don’t size the drive on Hp alone and Don’t forget the system voltage

•             The “Remember To things like” – location, altitude, enclosures

•             Uh – OH’s like long motor leads and non-invertor motors

•             Maybe a little single phase talking or off the power point topics like harmonics

•             And certainly, during the course we will cover some problem areas and even troubleshooting
