Load bank testing is commonly carried out in industry as a method of preventive maintenance. Whether they’re annual tests or weekly ones, load banks can be crucial in alerting officials about the capabilities of appliances like generators and UPS (Uninterruptible Power test bank) systems to cope when mains electricity fails.
So where exactly is testing applicable and what types of the device are available?
By simulating an electrical load, load banks can test an array of power sources. For example, testing is essential in the maintenance of diesel generators, and can also be used to test out new engines and equipment before they are installed in a factory. Additionally, they are used in testing UPS systems, and are instrumental in establishing the battery life of cells within a UPS and helping personnel determine when they should be replaced.
However, they aren’t only important for industrial purposes. They’re also used by hospitals, the military and airports to test equipment to ensure that there is no disruption to services if mains power fails. In this way, they’re valued by public services and institutions, and not just commercial enterprises.
Types of the device
There are three different types of the machine. The first and most common is the resistive. In this type of load bank an equal load is applied to the generator as to the prime mover (the mechanism that converts energy into motion). This type of generator can simulate real life loads like heating and lighting and may be available in a range of types, including AC and DC configurations.
The second type is the reactive one, which may be inductive or capacitive. And the third type is the resistive/reactive, which combines both previous types.
If you’re not sure what kind you need, consider renting from an established company for access to a range of different types and knowledge on how to use them. Rental companies will be able to tell you which kind of load banks you need and advise you on how regularly to carry out preventative maintenance of your equipment.
