WebResistive load elements can produce precise amounts of load at a power factor equaling 1. Resistive load elements generate large amounts of heat that must be quickly dissipated to prevent overheating. Consequently, load banks use forced air to cool resistive elements, which is provided by a dedicated power circuit and one or more blowers.
