4 types of load banks

 

Four types of load banks can be used to test generators. Each type of load bank has its advantages and disadvantages.


1. Resistive
Resistive load groups are the most common. The resistive load bank allows you to test prime movers and generators at 100% capacity. This method uses a simple method to measure the load: electrical energy is converted into heat through a resistor, and the heat is dissipated through air or water.

This type can simulate actual load, including prime mover capacity (kW), prime mover control and transient response (Hz), but for alternator capacity (kVAR), alternator control, load sharing control (only kW) test Limited capacity, distribution bus and transient response (voltage).

Resistive load bank is most suitable for: generator, portable generator, small generator UPS system with a capacity of less than 200 kVA.

2. Reactivity
The reactive load bank tests the load through capacitors or inductors in the load. This process is the process of converting electrical energy into a magnetic field. Inductive loads are more common than capacitive load groups. The inductive load group can only test up to 75% of the full power test, while the capacitive load group test has almost the same performance, except that it creates a leading power factor load to simulate certain electronic loads and nonlinear loads.

The reactive load library is suitable for testing motor-driven equipment and transformers, usually equipment in the telecommunications and UPS industries.

 

3. Combined resistance/reactance
The combined resistive/reactive load library utilizes the characteristics found in the resistive load library and the characteristics that the latter cannot measure. Resistance/reactive load box can be tested:

Prime mover capacity (kW) prime mover control alternator capacity (kVAR) alternator control load sharing control (kW and kVAR) distribution bus transient response (Hz) transient response (voltage).

The resistive/reactive load library is most suitable for: generators with a capacity greater than 200kV, with a single generator and multiple generators starting from 1 MVA.

4. Electronics
Electronic load library can test average load capacity and peak load capacity. To perform the test, an electrical load is applied to the power source. Compared with the results obtained from other types of load libraries and tests, the electronic load library has advantages and can generate more accurate data. The disadvantage is the price-electronic load box testing is more expensive. The electronic load library is programmable and can be used to test generator systems of all sizes in any given industry.

 

As you can see, load library testing is necessary or even necessary, but there are many options to consider. We can help you determine the best option for your operational needs and emergency plans. Our goal is to keep power on even in an emergency.
