How do you size a bank load?
KW varies as the square of the voltage change and can be calculated using the following formula: KW output = Rated kW x (Applied Voltage/Rated Voltage)2. Therefore, in the preceding example, if the load bank terminal voltage is reduced to 473v, then the resultant KW will be 97% of the rated KW.

How does an inductive load bank work?
Inductive Load Banks This provides the capability to test the generator set fully at 100% nameplate kVA rating. Inductive load banks add inductance to the load and therefore reduce the PF to less than unity (typically 0.8pf on diesel gen-set). Inductive load banks are rated in kilovolt-amperes reactive (kVAr).
What is load bank equipment?
A load bank is a piece of electrical test equipment used to simulate an electrical load, to test an electric power source without connecting it to its normal operating load.
What is a DC load bank?
What is a DC Load Bank? A DC load bank allows for testing and analysis of generators, battery systems, uninterruptible power supplies (UPS), and other electrical systems. The load bank creates an artificial DC load for the electrical system, changing the load to replicate legitimate use of the system.
What is a portable load bank?
Portable load banks are built to transport safely to job sites, including remote locations. Once onsite, portable load banks are designed to be easily moved from one testing location to another.
Who makes Avtron load banks?
Steadypower offers quality Asco Avtron portable, mobile, and stationary load banks with max capacities as low as 25kW and up to thousands of kW, in a variety of single and three phase voltages, including medium voltages. Resistive, reactive, capacitive, and resistive/reactive models available.
What is a resistive load bank?
Resistive Load Bank Uses Light bulbs, lamps and space heaters are examples of tools that convert electrical energy into heat. These types of load banks draw a specified real power load, in kW, on the generator to ensure the operation of the power supply’s cooling system, exhaust and engine operation.
What is inductive load example?
Reactive/Inductive Load – An inductive load converts current into a magnetic field. Inductive reactance resists the change to current, causing the circuit current to lag voltage. Examples of devices producing reactive/inductive loads include motors, transformers and chokes.
Is a light bulb an inductive load?
An excellent example of a resistive load is an incandescent light bulb, which takes all the power and uses it to create heat, generating light.
How does a Loadbank work?
Load banks are used to commission, maintain and verify electrical power sources such as diesel generators and uninterruptible power supplies (UPS). The load bank applies an electrical load to the power source and dissipates the resulting electrical energy through resistive elements as heat.
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.
