What is a Load Bank?
Load Banks are devices used to test and commission any electrical power source, providing electrical load to power supplies to simulate service loads.
Load Banks convert the electrical load coming from power sources such as generators, gas turbines, UPS, alternators and transformers into heat with the help of resistive elements (Cr-Al) in it and ensure that it is removed from the system with strong fans. In addition, load banks are also used as Dummy Loads to prevent “wet-stacking” problems of diesel generators, apart from testing and verification. When diesel generators operate at values lower than 30% of their rated value, the problem known as wet-stacking occurs and causes the generator to fail over time. Many generator manufacturers do not provide warranty for generators and turbines operating in this way. That's why automatic load banks are used. |
Applications
Load Banks have wide usage area in different industries. The main areas of use are listed below.
|
Load Bank Types Load banks have different groups according to the load element they contain. Resistive Load Bank (kW) It is the most widely used type of load bank. It contains resistive load elements to load the power supply. They are produced by using Cr-Al resistance wires or high heat resistant sheets. These load banks have a Power Factor of cosø :1. |
Inductive (Reactive) Load Bank (kVAr) They contain "inductive" load elements. Also known as reactive. Coil with copper wire wound is used to form inductive elements. Unlike resistive loads, inductive load current follows a sinusoidal pattern, with the voltage peaking after the sine wave, so the maximum, minimum, and zero points for voltage changes are out of phase with the current. As a result, inductive coils produce lagging power factors. |
Combined Type Load Bank (kVA)
It is a type of load bank that contains both resistors and inductive coils in the same cabinet. The resistive and inductive elements inside can be operated separately or, if desired, the power factor can be adjusted by operating them together (cosø : 0 – 1). It is often used to simulate systems affected by electric motors or electromagnetic devices in a network or system.
General Features Load Banks can be produced with various cabin types and ventilation types in accordance with different needs. In order to get the right result, these issues should be considered when choosing a load bank. Load Bank Protection Classes If the Load Bank is to be used in a closed environment that will not be affected by environmental conditions, it can be preferred with the Indoor Type Cabinet with IP20 Protection class. If it will work under a shelter in an external environment, cabinets between IP20 / IP31 will be suitable. |
Apart from these, outdoor type load banks with IP31 and IP 56 protection classes can be produced that can operate safely in the outdoor environment without any extra precautions.

Portable Load Bank They are generally devices with a capacity of up to 100kW. Since it is used for service and maintenance purposes, it has easy-to-carry wheeled cabins or carrying bags. |

Container Load Bank Container type load banks are designed to withstand the rigors of both shipping and weather conditions. And due to its standard dimensions, it is also advantageous in terms of logistics. |
Trailer Type (Mobile) Load Bank It is mounted on a trailer designed according to its capacity and transported by a vehicle. Useful for capacities between 200kW and 5MW. In addition, trailer options suitable for traffic are also available. |
