Have you heard of load banks? These are useful electrical equipment for testing, calibrating, adjusting or verifying your power source.
A load bank is electrical testing equipment. Using a load bank, you can stimulate a full electrical load on your power source, without the risk of connecting it to its normal power source. You also don’t have to expend the same amount of power. The bank receives the power back and turns it into heat. A cooling system, either forced air or water, removes the heat.
There are portable and permanent load banks. You can use a portable load bank with portable equipment or as a rental to occasionally test your equipment. If you have a large and permanent power supply, then it is best to have a permanent load bank installed to use regularly.
Anyone who needs to test, calibrate or verify the operation of an electric generator, diesel generator, battery, or other power equipment needs a load bank. It is especially important for emergency backup systems, which will not be under regular use but which still need to be tested in order to ensure they will be ready when they are needed. Load banks are used in a variety of industries, including data centers, wind farms, utility substations, microgrids, oil, gas and nuclear, government and military, maritime, healthcare, and hospitals.
There are different kinds of load banks, including:
These kinds of load banks are usually used for AC voltages, although you can also find resistive options for DC voltages. If you are using it on a generator, it will achieve 80% of the kVA rating. It will also fully load the cooling, fuel and exhaust systems so all of these may be tested.

Reactive load banks can’t test a system at full capacity, but they are generally better at simulating real-life scenarios. To test maximum load, reactive load banks are used with resistive load banks in order to get a generator up to 100% of the kVA rating. Using reactive load banks is important when you need to test the full functionality of a generator in various situations.
A reactive load bank can simulate an inductive load in addition to a capacitive load. In inductive load, current lags behind voltage, whereas in capacitive load, voltage lags behind current.
Reactive load banks are best suited for testing devices and transformers that are motor-powered. In these cases, electrical energy is converted into a magnetic field which drives motor rotation. As such, reactive load banks are most effective at evaluating transient loads and testing alternator capacity.
Reactive load banks are often needed for commercial systems, such as those used in construction, telecommunications, and emergency backup power supplies. Need a reactive load bank for your business? Chat with our reactive load bank sales team today!CONTACT US CONTACT US
A site load correction uses a load bank to proactively increase loading on diesel gen-sets to avoid the effects of wet stacking. It can also be used to ensure that generators are run at higher levels for optimal performance and reduced emissions. When necessary, the load bank automatically applies load, and ensures that gen-sets reach the proper operating temperature for user selectable time periods.CONTACT US CONTACT US
These load banks are more precise and functional than other load banks. Instead of applying the entire load, operators can instead apply exactly as much load as they need to for testing. Depending on the specific load bank, your staff may be able to select a load as small as 1 kWAr, or as much as the full load of the equipment. They are most commonly used to adjust the power factor.
