Load Bank Testing

The load bank tester is connected directly to the generator output. Load bank testers are used in place of a facilities load. This device develops an electrical load to test for generator output power.  As the load bank tester increases demand, the generator systems are tested to full capacity. Those systems include enclosure louvers, engine fuel system, engine cooling system, engine air intake system, and the voltage and amperage of the generator itself.
