Your generators represent a sizable capital investment. This important preventive maintenance test monitors the engine system and generator outputs. Think about it – if your generator fails to perform properly when you need it, the results could at their worst, be catastrophic, and at their best, carry big financial consequences. That’s why it makes sense to do periodic load bank testing as part of your comprehensive preventive/predictive maintenance program, so you know for sure that your genset is capable of accepting certain loads when required.
A generator typically runs at a level less than the unit’s rated output capability, so a load bank test provides an artificial load that brings the engine to an acceptable operating temperature, ensuring that it will perform appropriately when you need it. In addition, over time, lightly loaded generators develop wet-stacking and carbon buildup in the combustion chambers and exhaust system, which can lead to increased oil and fuel consumption and poor engine performance. As the generator ages, other potential enemies – weather, pests and age – can negatively affect its efficiency. The use of a load bank test helps prevent this and determines the generator’s capability to produce maximum output in terms of amperage and horsepower.
The test gives you peace of mind that your generator will remain reliable throughout power interruptions.
