Introduction to Load Banks

In our last blog, we discussed the importance of carrying out load-bank testing for your generator. We also promised you that we’d be discussing the equipment used for load bank. Well, the primary equipment used in load bank testing is a load bank.

So, what are load banks? That’s what we are here to find out.

Load banks are critical assets that any business should consider investing in. The main function of a load bank is to ensure that certain equipment are capable of operating according to expectation. More specifically, load banks, as we discussed earlier, are used to test generators and check if they can handle the maximum load possible.

How Do They Work?

Load banks basically create an artificial load similar to everyday load. This load is then supplied to the generator to see if it can handle it. They replicate the original load, which means unpredictable or random currents are impossible.

Load banks exist as a contained system with accessories and controls in a single location. The power source itself supplies the power while the load sues this power to protect the source and also test it at the same time.

Applications

Load banks can be used in a wide range of settings. They can be used to test battery systems, ground power units, auxiliary inverters, and even engine generators (wind, aircraft, and hydro).
For instance, in engine cell testing load banks help test the efficiency of engines under varying circumstances. The load bank is connected to the engine using dynamometers. Once connected, it measures performance and adjusts as necessary.

Similarly, load banks are used in generator cell tests. The load banks help generate various loads that help check the stability and endurance of generator cells. If there are problems, the load bank will calibrate the generator, which makes it possible for the generator to adhere to the suggested tolerance levels and other specifications.

Load banks are also used to test diesel generators. They make sure that the unit uses the fuel as it should. When the fuel consumption is not ideal, it leads to wet-stacking. Wet-stacking is the result of oil and grease accumulation. This accumulation interferes with the diesel generator’s normal functioning and efficiency.

So, it’s always good to invest in a load bank or hire the services of load-bank testers. Generators need to be checked on a periodic basis to ensure that they are capable of optimum performance.
