Load banks to control
the operation of power generators
For permanent and efficient maintenance of all types of generators
A generator is a heat engine associated with an alternator that generates an alternating current. The coupling to a load bank allows to test it, to validate its power, to regularly defoul it, or to weight it, according to how it has been used. The proper operation of the generating set and its performance over time depend highly on the regularity of these tests.
Whether it is a rarely used emergency gen set tested on a monthly basis, or a rental one that returns or goes out for rental and whose owner wants to prove the proper functioning to his client, the full load test is the only guarantee of a generator’s good functioning and power handling, without cutting or disrupting the network with real tests.
Indeed, many faults and failures occur only at full load, a vacuum test would not be able to diagnose them while further fouling the power generator.
At low load an engine does not reach its optimum operating temperature, the engine gets clogged or suffers from ‘wet stacking’. Therefore it is necessary, after a long period of low load, to “clean” the engine by running it at least at 80% of its rated capacity for several hours.
The load bank also allows the engine to be run in after some heavy maintenance.
A load bank with weighting option is able to measure the power supplied on the network and trigger the resistance notches required to achieve a minimum power of 30% to 50% of the gen set rated capacity.
The generator then operates in its right temperature range, with a better yield while limiting fouling issues.
Most of the time, a load bank is used to test a power generator. Load banks are intended for numerous generator users: energy consumer or industrial producers, but also installers, rental or maintenance companies, etc.
Each type or use of generating sets requires a proper load bank. Whether the generator runs regularly, is coupled to a supplier’s network, works only occasionally, or needs weighting so as not to run empty, there is a specific load bank to meet your specific situations.
KVA studies your requirements and provides the most appropriate load bank.
Depuis plus de 20 ans, nous utilisons les bancs de charge KVA Applications. Nous sommes entièrement satisfaits de ces produits robustes et fiables.
We bought a load bank that works perfectly for the test of our emergency generator.
We bought a reliable and robust bank that has never had any problems since 2011. We like the 1kW resolution as well as the easy handling.
Our KVA Applications test banks have been running 24 hours a day for 2 years. We greatly appreciate the support of KVA throughout this project.
We appreciate the modularity of the KVA banks that enables us to develop a wide range of resistive and inductive load solutions for our installations.
