Why do you load test generators
Load Banks are devices designed to provide electrical loads for testing power sources such as generators and Uninterruptible Power Supplies (UPS). Load banks are also used to reduce "wet stacking" problems in diesel engines of backup generating systems.

The primary cause of diesel engine failure is "wet-stacking" ("wet" unburned fuel accumulating in the engine "stack"). It is caused by under-loading of the generator. Diesel engines that are lightly loaded, or allowed to idle for long periods, never reach their recommended operating temperature. Over time, unburned fuel coats the combustion chamber, reducing engine rating, efficiency, and life span. A preventive maintenance plan that includes load testing of a diesel generator set, will reduce the harmful effects of "wet-stacking" and increase engine life.

Industry trade organizations and manufacturers both agree that a well planned preventive maintenance program is vital to the reliable operation of a standby generator. Load Banks are an essential part of such a program. Load Banks provide a practical means to test the system without interruption to the critical loads.

Load banks can be used in a wide variety of applications

Factory testing of engine generator sets

To reduce "wet stacking" problems

Periodic exercising of stand-by engine generator sets

UPS system testing

Battery system testing

Ground power testing

Load optimization in prime power applications

Factory testing of turbines

UPS Load Testing
Your business cannot afford to take chances with your critical electrical loads. With more of the data in the operation of business being critical to the continued successful operation of the today's business, it is very important to protect your data from power problems. The investment in UPS load testing can save your business from future down time and hardware failure due to battery life r problems. This can result in a large amount of savings for a business over the life of the UPS system.

Battery Run Downs
Only at certain times should a battery run down be done on a battery system. The installation of a battery system, it is the best time to due a battery run down test. This is done with load banks to make sure that the batteries meet the required runtime and that there are no installation problems.

Remember that every time a battery is discharged, a little bit of the battery's life dies. Because of this, SCI does not recommend battery discharges all that often.
