Because many generators do not regularly operate at their full kW rating, it’s especially important that you verify your generator can actually produce the highest possible horsepower that may be required – while at the same time maintaining adequate temperature and pressure levels that will allow it to run as long as necessary.
A load bank test ensures that your generator will run property when it’s needed so that you can fully depend on it during an emergency situation. The key to a proper load bank test is that it tests your generator at its full kilowatt (kW) output rating.
When a load bank test is implemented, an artificial load is placed on the generator. The test is timed and gradually increases the kW load in specific increments. Each time the kW load is increased, engine and alternator parameters are recorded. Testing the generator’s ability to handle the boost, and its ability to continue functioning at the highest possible level for a sustained period of time. The equipment needed to complete the test includes a load bank (machine with kW rated sizes and battery like cables).
