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 Load Bank is intended to accurately mimic the operational or “real” load which a power source will see in actual application. However, unlike the “real” load, which is likely to be dispersed, unpredictable and random in value, a Load Bank provides a contained, organized and fully controllable load. Consequently, a Load Bank can be further defined as a self-contained, unitized, systematic device which includes both load elements with control and accessory devices required for operation. Where the “real” load is served by the power source and uses the energy output of the source for some productive purpose, the Load Bank serves the power source, using its energy output to test, support or protect the power source.
Introducing Paarsun load bank
The Paarsun load bank is HMI/MAN controlled resistive-reactive loads designed for general purpose AC generator testing.
Load bank is designed to provide a determined load on the generators with very varied load step resolution.
The load bank are manufactured from corrosion-resistant.
A gland plate is designed for fast temporary power connection.
The resistive elements are cooled by naturally airflow or a direct, forced airflow provided by an axial fan (or fans).
A differential pressure switch (DPS) is used to ensure correct fan blower rotation in air forced cooling. The input and output ducts are protected by stainless steel mesh screens.
All of the electrical and controller components are housed control panel box, which are fitted with lock that provide protection up to IP54.
Load bank is fitted with a lifting frame which provides additional strength, and allows the entire load bank to be lifted and maneuvered into position by crane.
The nameplate of load bank describes load bank specification completely.
A cooling unit could be installed on control box to cooling it in harsh climate.support or protect the power source.
Applications
Load Banks are used with Engine Generators, Battery Systems, UPS Systems, Inverters, Ground Power Units, Auxiliary Power Units, Aircraft Power Generators, Wind Generators, and Hydro Generators. Load Banks can be used for several purposes, including:
