The Importance of Load Bank Testing Generators
Your business depends on electricity. That’s why you’ve proactively invested in generators to make sure you still have power even when the grid goes down. Just like any major property system, generators run better when they receive the right testing and maintenance.
Running a generator efficiently helps it last longer and run reliably. Many generators, especially backup generators, rarely operate at capacity. When a generator runs at 30% or less of its rated kW load, this is known as light loading. Consistent light-loading generators can increase operating costs and wear and tear. In diesel generators, problems can include wet stacking, which is a buildup of unused fuel and soot in the unit’s exhaust system.
Under the NFPA and NEC code requirements, load bank testing is required for many emergency power applications, such as hospitals and data centers. It’s one of the most effective methods of preventative maintenance for generators. In this blog post, we’ll explore load bank testing and how it can help keep your generator operating at its best.
How Is Load Bank Testing Performed?
Load bank testing verifies primary components work properly under optimally loaded conditions. It begins with an inspection of the generator set. Then, testing equipment — known as a load bank — creates gradually increasing operating pressures and temperatures to match target conditions.
Operating parameters observed during load bank testing include:
- AC voltage
- Amperage
- Hertz
- kW load
- Oil pressure
- And more
How Load Bank Testing Maintains Generators
Generators are designed to have a prime fuel-to-workload operating range. With consistent light-loading situations, underutilization of power can cause wet stacking. This buildup of residue in the unit’s exhaust line decreases power output, increases emissions, increases the risk of fires, and increases the need for maintenance and repair visits.
Annual load bank testing includes several benefits, including:
- Confirmation that the tested generator will run at its best when needed
- Cooling system testing
- Early identification of problems, meaning they can be addressed before they grow into something more expensive and prohibitive
- Removal of carbon deposits and results of wet-stacking
- Verification of the generator’s full operating capabilities
