The dummy load banks can be used as a ballast load during the normal operation of a generating set. In fact the connected load to the generator may vary over a wide range, either as seasonal variation or the load itself, and so when the real demand is small it can be useful to connect an additional load to allow to the engine operating at 40% of its rated capacity to prevent dangerous effects.
Another important application of the load banks is the periodic test of the diesel generator sets that should be always an essential part of any predictive and preventive maintenance plan to ensure that the standby generator sets operate in case of power failure. Consider, for example, the risks associated with the failure of the emergency power unit in a hospital, an airport, a data center, a shopping mall or in a bank. Usually the test of a diesel engine is run with very low or no loads making the generator sets increasingly unreliable and expensive to maintain. This mode of proof in fact generates phenomena such as wet-stacking (the accumulation of unburned fuel in the exhaust system) that lead as consequence an oil and fuel anomalous consumption, reduction of performance and reliability of the engine, increment of operating costs.
