18 December 2008 Australian Federal Police - Weston Data Centre Canberra - Emergency Generator Installation
Molec performed the following work on this project on behalf of Coote Energy: Ø Complete rewiring and additional modifications on a double-bus 415V, 2000A switchboard for controlling four 630A essential data-centre load circuits, a bus-tie, a 400kW load bank, and two Cummins 650kVA containerised (outdoor) generator sets, with provision for a third generator set. The switchboard contained automatic ComAp controllers for selecting either the mains supply or generators for powering the four load circuits. Ø Most of the 2000A copper busbar was removed for cleaning due to tarnishing through a sulphuric acid spill at the place of manufacture of the switchboard. Ø Modifications were performed to the generator on-board controls to facilitate interfacing with the controllers in the double-bus switchboard. Ø An outdoor control box was built and installed for a 10kL automatic bulk refuelling system for filling the generator 900L onboard tanks from the bulk tank. Ø A new metering switchboard (between the ActewAGL substation and double-bus switchboard) was installed to replace an existing metering board, performed in a single day as part of an extensive cutover plan for the essential load circuits between an original switchboard and the new double-bus switchboard. Ø Assistance was provided with commissioning the installation up to the point of final cutover.
