What is a load bank?

A load bank is a stationary or portable piece of equipment that provides an adjustable resistance that can simulate the actual electrical load the generator, UPS or any other electrical equipment is expected to power. This artificial load is intended to accurately mimic the electrical demands of the equipment(s), specific processes within the plant, or an entire facility. The test is performed to check the performance of the equipment to ensure that it would function efficiently, without break-downs when the actual load is used.

Why do you need a load bank?

A load bank is an easy to use and cost effective solution for the following:

1. Testing and maintaining electrical power systems during their installation and erection
2. Prolonging the life and efficiency of generators, UPS and battery systems
3. Avoiding excessive wear and tear of underloaded generators and other energy generation systems (ex: dump load for wind turbines)

What do we offer?

AESPL offers portable, tailor-made and cost effective load banks for various applications with extra safety features. Load banks are provided on rental bases as well as manufactured for specific requirements. A total capacity of upto 7 MW is available with us. Our load banks are being deployed for:

1. Testing gas generating sets
2. Testing diesel generating sets
3. Dump load for wind mills
4. Testing UPS
