Load Banks
Used to simulate an electrical load. METS Energy offers Load Banks up to 1500 kVA.
Over time, lightly loaded generator sets develop wet-stacking and carbon build-up in the combustion chambers and exhaust system.
The use of a load bank helps prevent this and determines the generator’s capability to produce maximum output in terms of amperage and horsepower.
The impacts of low load running potentially include:
- Increased lube oil consumption
- Poor engine performance
- Increased fuel consumption
- Crankcase pressurization
For engine only exercising and general engine maintenance a resistive only load bank is ideal for clearing carbon build-up in the engine, it is the most common and cost effective option for preventative maintenance.
Benefits to load bank testing
- Peace of mind– will the generator work when needed
- Regular load testing can increase the life and reliability of a generator
- Proves performance of the generator (resistive/reactive required for 0.8pf)
- Aids commissioning of generators for utility paralleling applications (resistive/reactive)
- Safe replication of emergency situations for new systems
- Demonstrate engine output for overhauled engines
