How Does a Resistor Bank Work

A resistor bank is the practical device available for the purpose. Operators effect changes in motor speed with various loads and operate a bank of magnetic contactors to achieve the desired operation. The contactors change taps on the resistor banks as required to maintain appropriate rotor circuit resistance.

How do resistive load banks work?

A Resistive load bank, the most common type, proves equivalent loading of both generator and prime mover. That is, 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.

What is load bank resistor?

A load resistor bank is a powerful energy equipment which generates loading equivalent to, say generators and prime mover. This means that for every kilowatt of load given to generator by load bank, equal load is transferred to the prime mover by generator.
