Audited Supplier Load bank testing solutions include load banks that test the operation of an electrical system. Load banks control the total load, power factor and schedule during the test. Many of the devices in an electrical system use sensors that measure current to determine their function. Electrical load needs to be added during a system test to ensure all sensors have adequate current to perform as intended.
There are three main load bank testing solutions: Resistive, Reactive and Resistive/Reactive:
Resistive Load Banks - The most common type, resistive load banks mimic the operational load that a power source will see in actual use. They convert electrical energy to heat using power resistors and dissipate the heat using air or water.
Reactive Load Banks - These solutions are used to simulate systems affected by electric motors or other electromagnetic devices on a power network. Typically, equipment that requires reactive power compensation are motor-driven devices, transformers and capacitors. Reactive Load banks can simulate either an inductive or capacitive load depending on the type of load expected on the power system
Resistive/Reactive Load Banks - These solutions combine both resistive and reactive elements in one load bank package. They may accommodate equipment up to 6250 kW. These load banks can also be used for integrated system testing of utility substation protection systems, particularly for more complex relays like distance, directional overcurrent, power directional and others.
