Load Banks are composed of a number of resistive or resistive/inductive units which are designed to operate in DC, 1-phase AC, or 3-phase AC network. The main application of Load Banks are as follows:
1- Test of Diesel Generators, Gas turbines, UPS, Industrial batteries, inverters and Switch-gears, in order to investigate the issues related to the design, efficiency, the output’s balance, and capacity of the units.
2- Load stabilization and reduction of power fluctuations
3- Load simulator in aerospace and marine industries.
In some cases, the load connected to the generator varies in a wide range (This variation is usually as a result of seasonal changes in the load or due to the variable nature of the load itself). When the real load decreases in the network, it will be necessary to add a number of Dummy Loads to the network so that the generator can operate at least in the range of 20% to 40% of its nominal capacity (base load). Therefore, the Dummy Load will require a load sensor relay in its control panel.
The main specifications of the Load Banks are as follows:
- Nominal voltage
- Nominal power
- Power factor
- Nominal resistance
- Nominal inductance
- Number of steps
- Number of phases
- connection type
Introducing PAARSUN load bank
PAARSUN Co. design and construct its Load Banks considering the above-mentioned parameters, maximum permissible temperature rise of the elements (according to relevant standards), cooling type of the system (Air Natural, Air Force, or Oil Natural), maximum temperature of the fan’s outlet air, and the available vibration in system. The Load Banks can be designed as manual/automatic, permanent/mobile, and single-step/multiple-steps.
