Understanding Resistive Load Banks in Generator Testing and Maintenance

A load bank is a piece of testing equipment that acts as a substitute for an actual electrical load by drawing power from an external source. A diesel generator, UPS, or any other electricity equipment may act as the power source. Load banks are used to put the power supply through its paces before it is connected to the regular load. They help configure the power supply to meet actual power demands by modeling the load. Heavy-duty resistors in the load bank and water or air cooling are employed to dissipate the produced heat efficiently.

Electric generators are kept on hand in case of power outages or other scenarios when they would be needed.

Since disasters may strike at any time, it’s essential to have a backup power source ready to go. Load bank testing ensures the generators operate at peak performance and efficiency. To replicate the effects of a real-world load, electrical energy is converted to heat in a load bank. Capacitive, inductive, and resistive reactive load bank from Junxy Energy are the three main varieties.

Maintenance of Fault-Tolerant Load Banks

The resistive load bank is the form of load bank that is used the most often because it is possible to use it to test a generator or another kind of power source to its maximum capacity. It is well known that the primary function of a resistor is to obstruct the flow of electricity while simultaneously converting the thermal energy carried by an electric current into heat. By using high-power resistors, resistive load banks can convert electrical energy into heat, which is then released into the environment around them by either water or air cooling. Because the resistive load bank transfers all of the energy from the power source into heat, it is feasible to run the generator through a test that simulates its highest potential level of output. The most typical kind of resistive load bank is one that is not heavy and can be moved from one generator to another without much difficulty. It has wire resistances that are relatively close to the cooling fans. The device’s purpose determines the amount of space needed for the resistive load bank. They might be transportable or permanently installed at one location.

Resistance Load Bank Applications There is a wide variety of uses for resistive reactive load banks. You may use them to test out anything from a few hundred kilowatts to several hundred megawatts of power, and they come in various configurations. A DC portable unit evaluates power sources such as batteries, UPSs, and DC generators.

In addition, uninterruptible power supplies (UPSs) and AC generators with a capacity of 150 kW are only two examples of the types of AC power sources that may be evaluated using portable AC equipment mounted on wheels. Inspections of generator installations with a capacity of up to 3000 kW may be performed using portable testing equipment. There are also stationary units that are used in the production of renewable energy sources such as wind turbines and others. They simulate high-demand energy production scenarios ranging from 4500 kW to 100 MW in capacity.
