  • Fowler Electric and Control System West replaced three aging Pump Variable Frequency Drives for the large 300 HP. 
  • The VFD control PG&E power to the pumps to allow them to run at the correct flow and speeds for the required matching sewer flows
  • Power frequency harmonics of the system were tested to ensure the pump system works smoothly.
