Prime Power Systems

System Features

  • Automatic operation of on-site power generators to serve a facility’s entire load
  • If desired, utility/generator paralleling controls can provide active synchronization and soft loading (using a utility-approved interconnecting protective relay system)
  • PLC controls
  • SCADA capable
  • UL listed

System Operation

In prime power applications, on-site generators are the sole source of electric power for a facility.

In such systems,  engine generators are run in response to connected load.  If load increases to a predetermined level, additional generators are automatically started, synchronized to the generator bus, and share load with the running generators.  If load decreases to a predetermined level, excess generators are automatically removed from the bus and shut down, returning them to automatic standby status.
