The phrase Load Banking is used in the power generation business to associate the process of applying a substitute electrical load to a generator system. The generator is sized larger than the applied emergency load and critical loads should never be disrupted or put at risk. Because of these factors, building loads are not necessarily the best choice to use in troubleshooting a generator or for full load exercises.

Question: I just installed a 375 KVA generator at my shop. Will I need to do something to control the voltage?

Answer: Probably not. Generators are controlled two ways at the same time. The voltage is controlled electrically by the power sent to the rotating field. The frequency or Hertz is determined by the rotational speed of the prime mover (engine). The governor controls the engine speed and holds it to 1800 rpm or 60 hz regardless of the load. The on board voltage regulator, though adjustable, automatically controls the voltage.
