Callaghan Engineering have designed and specified the back-up power systems for large data centre installations for a confidential client. The generators were both ‘open-type’ sets (housed in a bespoke sound-attenuated building) and containerised stand-alone sets located externally. The generators were configured so that they could be routinely tested with a load bank to ensure that the machine would start and accept block loads in the event of mains (utility) failure.
In addition, Callaghan Engineering personnel have previously designed and commissioned synchronising and G10 paralleling protection systems to allow generators to run in mains parallel mode. Owners of large diesel generating sets and CHP plant can receive significant payments from the national grid when they allow their machines to be called upon by the grid to produce power to aid grid stability.
