Resistive Load bank
Load banks are the test device that is used to generate dummy loads for UPS testing. A load bank is a device which develops an electrical load, applies the load to an electrical power source and converts or dissipates the resultant power output of the source in the form of heat. A load bank includes load elements with protection, control, metering, and accessory devices required for operation.
A Resistive load bank provides equivalent loading of both the generator and prime mover. This means that for each kilowatt (or horsepower) of load applied to the generator by the load bank, an equal amount of load is applied to the prime mover by the generator.
