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. A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.

What is resistor bank. If the temperature of the bank becomes. Last week pdma reinforced the need to isolate the wound rotor from the external resistor bank to properly test its resistance to the shaft in order to help prevent flash over in the vicinity of the slip rings. 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.
They are connected in parallel to decrease the resistance and increase current rating and power. For todays demanding industries. Hence the resistor used in this process is known as braking resistor and the process is called dynamic braking.
Operators effect changes in motor speed with various loads and operate a bank of magnetic contactors to achieve the desired operation. Resistor converts the consume energy into heat and at the same instant braking effect is created. A resistive load bank therefore removes energy from the complete system.
A load bank is intended to accurately mimic the operational or real load which a power source will see in actual application. This large amount of energy is consume by the resistor which is present in a power circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor.
A resistor bank is the practical device available for the purpose. Load bank from generatorgenerator from prime moverprime mover from fuel. Many technicians simply lift the brushes to accomplish this isolation from the external.
In simple way resistor bank contains number of resistors in series or parallel combination. A resistive load bank the most common type provides equivalent loading for both generators and prime movers. Read more about load bank fundamentals at simplex.
