Electrical design will take into account the level of resilience most appropriate to the requirement of your organisation. The switchgear for data centres can either be of the standard “off-the-shelf” type or be purpose made for a specific application. In either case it must be designed such that:
With proper design, standard switchgear can be made to meet the above criteria however but it does have limitations. For example, on occasions it will be necessary to isolate a switchboard. With dual A & B supplies this does not necessitate shutting down the room but it does mean the room is on one supply for a time, and so is at risk.
Thamesgate can design and build switchgear purpose made for the particular application which allows us to meet other requirements, e.g. metering, bus-couplers, isolation transformers ‘Castell’ interlocks and so on, can be incorporated. Bespoke switchgear may appear more expensive initially, but over the life of a data centre it will pay for itself in lower maintenance costs, increased functionality and reduced risk.
