Diesel engine power generators are one of the most important components of an industrial emergency backup plan. In emergency situations a failure of a power generator can lead to a catastrophic situation. It is important for companies to monitor and maintain the performance of their power systems. This is where load bank testing comes in handy and helps facility managers maintain their power equipment. Load bank testing uncovers potential problems in power generators and enables managers to take preventive measures.
Load bank testing is probably the most effective technique for ensuring efficient operation of a backup generator. No matter the nature or type of load bank system, it can not only test the equipment but also improve the overall health of the backup units. Load bank testing is a process:
Check cooling system operation
A load test injects excess heat into the cooling air stream to the generator. This process will indicate a malfunction in the cooling system. The extra heat generated during the process also puts stress on the components of the cooling system: thermostat, oil cooler, radiator, etc. We can also get valuable data from a test procedure that can help us with temperature differences. The temperature data backup also helps verify unit compliance. This procedure verifies operation of cooling system alarms such as the engine coolant overheat and high cooling water temperature alarms.
check fuel system operation
The latest diesel engine models are highly turbocharged, which makes them prone to poor combustion at low loads and over-fuelling. Sometimes power systems do not operate at sufficient load to generate flow velocities and high exhaust temperatures. This condition can lead to issues such as a wet sump or an accumulation of debris in the exhaust system. These problems can seriously harm the overall performance of a backup system; Operation in unloaded condition or continued use at less than recommended level of load may reduce engine output efficiency.
check control operation
A generator’s power supply and controls are sensitive to customers, and may shut down unexpectedly when the load changes. An inductive or resistive load test is the best way to ensure smooth generator operation. A reliable test procedure can help uncover many electrical and operational issues such as voltage and frequency adjustments, failed connections, circuit breaker trip settings, and voltage regulator performance. It also provides a best-case simulated real-world situation where efficiency, harmonics and voltage drop can be effectively studied.
These are some of the benefits of load bank testing. Make sure you are taking good care of your power tools and generator set. You can hire a private company to deliver rental load bank testing and preventive maintenance services at your doorstep.
