What load banks are?
The load bank is a simulating load testing equipment used for the testing of generators. The reactive load bank is that type of load bank which is mostly used for testing the different electrical types of equipment like batteries, generators and electric motors. This is done by taking the engine to a certain working atmospheric pressure and temperature to visualize the mechanism of the equipment to be used in an emergency. Load banks can also be installed earlier in a setup or linked continuously to an energy source, or simple variants are available to test sources of energy like reserves batteries and electric generators.
What are Reactive load banks?
Marine load banks are the type of load banks used for testing the engine of the generator at its rated power factor. The power factor is usually used for measuring how efficiently our engine is working in the generator, whether it is given full power or not whether it is giving stable power on the actual working load (high or low).
The construction of the reactive load bank contains resistor, inductive, capacitive and electronic load bank.
- In the load bank, resistors connected in load banks. Every resistor got the energy to simulate a linear load to the generator.
- The other major part of the reactive load bank is inductive. This is the major component in the load bank which is an iron core reactive element. When the resistive load used side by side with the inductive, it produces the power factor type of load. It is normally used for the loads which consist of transformers, lightening, motors, etc.
- There is one more major component of the tester which we called the capacitor. The power factor changed to the leading power factor means the current leading factor with the help of dielectric material used in the capacitors.
- Kind of tester which has the design of water-cooled or air-cooled and is fully programmable. Kind of testers which simulate solid state of load and for precision testing getting constant power.
A reactive load bank should be used to check a generator or control source at 0.8 control in conjunction with a resistive load bank.
To set a specific power factor, you need a reactive load bank. Reactive loads do completely qualify the operating capabilities of the generator. It is planned for consistency in process. The difference between reactive and resistive KVAR is 0.8. Phases in this bank are divided in only one phase and sometimes its three phase iron core reactors.
Devices 3, 75 to 375 KVAR load steps are accessible in normal dimensions with 375, 450, 600, 750, 900, 1125, 1500 and 1875 KVAR. The standard ratings are 480 V, 3-phase, 60 Hz and 240/480 Volt are dual voltage units.
The K841B is used for the testing of diesel generator sets, continuous energy supplies and other AC energy supplies that needs to be check, checks with a power factor of less than 1.0.
