Load Bank Testing – Are You NFPA 110 Compliant?

Confirm your standby power systems are ready to work when they are needed by incorporating load bank testing into your generator set preventive maintenance.

Because your generator set my run infrequent, or when it does run, it may have little or no load, it is more likely you may experience a problem. Lightly loaded operation will not allow proper testing of cooling system components, engine safety shutdowns, and in diesel engines will result in build up of carbon deposits in your engine.

Load banking your generator set annually will:
Exercises cooling system components
Allows safety shutdowns to operate in real conditions
Helps eliminate carbon deposits
Tests the full output capability of the generator set

Preventing the Preventable
Resistive load bank tests simulate the demand a generator set must meet upon startup. The test confirms system ability to crank out a given kW and deliver an equivalent amount of kVA at unity power factors.

Additionally, resistive/reactive load banks test generator sets with a more realistic load, exposing both the engine and the generator to the loading experienced under actual, building load.

Determine Your Testing Schedule
Eliminate problems brought on by periods of low load operation by performing load bank testing annually. We here at Midwest offer the most extensive testing capabilities in the industry and can supply rental units if repairs or extensive service require downtime. Also, conducting weekly test operations under no-load or light-load conditions does not substitute for proper load bank testing. When testing your generator weekly, it is best to load to at least 30% capacity when operating.

Along with periodic maintenance, load bank testing offers the best solution for ensuring your generator set starts when you need it.
