Load Banking Services

A load bank is a self-contained unit which is used to apply controlled load on a power system. 

Since emergency generators are sized so that they can be able to accommodate full start-up load of the facility they are supposed to supply with power, most emergency generators are sized above the normal operating load if they don’t have load management system. This serves as a guarantee that the generator will be able to produce enough energy for the whole facility.

Ideally, load banking is a system which is used to determine the maximum backup power performance of a system. This technique should be performed regularly to make sure that the performance system is running efficiently.

Load banking can be used to:

• Verify system operation

• Commissioning and maintenance of a system

• Certify system capacity

Why perform a load bank test?

This test is carried out to ensure that the back-up generator is running to its full potential to make sure that it will be able to provide enough power when needed. Since emergency generators are sized so that they can be able to accommodate full start-up load of the facility they are supposed to supply with power, most emergency generators are sized above the normal operating load if they don’t have load management system. This serves as a guarantee that the generator will be able to produce enough energy for the whole facility.

Most generators are sized to about 30% or more of kW rating of a facility. This is important to regulate the surge of the building, as well as the equipment, start-up load. However, this challenges diesel powered generators because it can develop conditions such as wet stacking and carbon build up (in piston rings, turbo chargers, injector nozzles, combustion chambers and exhaust piping).
