The projects team at Server Room Environments provides a complete data centre UPS management service using the latest energy efficient, sustainable and eco-friendly power technologies. We can design and deliver power protection plans for any size of UPS system including complete electrical installation, commissioning, site testing, training and 24/7 maintenance contracts. Our experience covers single and three-phase UPS systems, modular transformerless and transformer-based uninterruptible power supplies, standby power generators, static transfer switches, power distribution units and LV switchboards; the complete critical power path to the incoming building transformer or substation to the IT loads.
Designing a power protection plan for a data centre is very similar to that of a server room but on a much larger scale. Most plans refer to protection of the critical power path. This follows the route of electrical supplies from the building incomer and point of common coupling (PCC) to LV switchboards and then its distribution around the data centre facility. Larger mega-sized data centres may have their own HV/LV transformer connection.
Data centers typically look for redundancy in their critical power path and cooling systems designed using the Tier principle from the Uptime Institute. Data center UPS resilience can be described in terms of the levels of redundancy provided in their design. The levels start with Tier 1 and basic protection of the critical power path with no redundancy and move up to Tier IV which provides multiple redundancy levels including connection to the grid from two separate transformers (2N: A and B supplies).
The back-up power element within a data centre will generally consist of an uninterruptible power supply and standby power generator. These may be arranged as single or N+X redundant installations with the UPS system housed in a plant room along with its battery set or within the data hall itself.
The biggest growth trend in data centre power protection is the adoption of modular UPS technologies. Modular UPS systems can achieve operating efficiencies of 96% or greater in full on-line mode and maintain this over a wide load profile (from 25-100%). Traditional transformer-based UPS systems achieve around 70-75% operating efficiency and only when around 80% loaded. In a data centre environment, modular UPS systems provide more opportunities to save energy through right-sizing the load and prepare for future expansion. A modular UPS frame can be installed along with all the necessary switchgear and power distribution to accommodate future expansion through the installation of additional UPS modules.
Server Room Environments has built an enviable reputation for its expertise in data centre UPS and power protection and energy efficiency. We provide an outstanding customer service including 24/7 technical support and fast-response maintenance contracts. In addition to our electrical installation services, Server Room Environments can also provide temporary power supplies including load banks and containerised systems. These can assist during commissioning, maintenance or as additional emergency measures. We also provide third party inspection and testing services.
