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

Utility electric bills contain not only a wealth of information about energy consumption in the utility, but also useful data about the utility water operation. Careful study of these bills and their historical trends can lead the utility manager to significant cost savings and improved utility operation. This course takes the participant through the significant parts of typical utility bills in easy to understand steps that can point to operational adjustments that improve energy management and save dollars.
* Understanding of the electrical billing process, including the function of meters.
* Knowledge of how to read a utility bill and locate identifying important information
* Knowledge of problems with energy waste and improper metering
* Understanding of operational adjustments that can improve energy management and cost savings
