The continuous growth in Data Centres and the importance of reliability and controlling capital costs has resulted in the installation of 11kV generators as a reliable back up source of power. The 11kV generator reduces the footprint that is taken up by low voltage generators and provides more power per unit. A significant reduction in the cost of back-up power is the final result.
Ultegra Supported Penske on this project by designing the earth grid required to undertake a full high voltage Site Acceptance Test, including but not limited to the design and installation of 11kV infrastructure, calculation and setting of protection settings, installation of earth grid, functional testing of protection schemes and final acceptance and sign-off.
The installation consists of an 11kV generator, 11kV Switchgear supplying 2 X 11kV/415V step down transformers and 2 load banks. At full load this system provides over 5,000 Amps at 415V.
