Emergency systems

Load banks
to test electric generators for backup systems

A particularly sensitive area: testing the power generators of emergency systems,
to ensure the continuity of the power supply

 

Discharge banks to check the batteries capacity

Direct current is highly present in specific applications and embedded systems, through batteries. Depending on the different technologies it is necessary to discharge them regularly to check the capacity of these batteries. There are a lot more regulations than for AC, so KVA Applications accompanies you by designing the right product for your required voltages and amperages.

Load banks can be used in three
complementary ways

To ensure permanent operability

Emergency power generators work sporadically when there is a power failure. It is therefore necessary to maintain them regularly so that they are operational when the time comes. Proper operation of backup batteries and generators becomes essential in the event of an electrical failure. The intermittent or permanent coupling of these generators to a KVA Applications load bank is therefore essential to regularly check their readiness.

To respect regulations for the safety of public institutions

In France, the fire regulations for tower blocks open to public impose recurrent tests of backup power supplies, and require to be:

  • Monthly;
  • At 50% of the rated power of the source (dimensioned for the supply of all the building backup systems);
  • For 30 minutes ;
  • With automatic start.

KVA Applications assists you in testing your backup power generators.

Un banc de charge pour chaque système de secours

Si la sécurité des personnes a été le moteur de ces règlementations, la même logique de test est appliquée sur des sites où l’interruption d’alimentation peut entrainer d’importantes pertes financières. Notamment pour les data centers, les lignes de production de gros volumes ou les élevages de grande taille. On peut citer la panne d’alimentation électrique subie par Delta Airlines, en 2016. Elle avait cloué au sol l’intégralité de la flotte pendant une douzaine d’heure. Les groupes électrogènes de secours n’avaient alors pas pu assurer leur mission.
