Siemens is one of the world's leading suppliers of components and systems to companies in the energy and electricity industry. With roughly 83,500 employees, Siemens Energy Sector had sales of over EUR 12 billion and received new orders for approximately EUR 22.6 billion in fi scal 2007. Siemens Energy Fossil is a division of Siemens Energy Sector. Siemens Energy Fossil - Field Service in Nottingham oversees the repair, service and upgrade of Siemens gas and steam turbine generators in the UK, including the Parsons steam turbine generators that are still in service across the globe, as well as other non-Siemens manufactured equipment. This work is undertaken primarily for electrical utilities and other industrial customers.
Specific tasks of the Siemens Energy Fossil - Field Service, are to service and repair hydrogen and water-cooled electrical power generators in the UK and worldwide. Andrew Reynolds is a service engineer at the Siemens Energy Fossil - Field Service.
Typical equipment serviced by the Siemens Energy Fossil - Field Service is the Siemens generator. These generators, with water-cooled stators and hydrogen-cooled rotors, are optimal for large steam and nuclear power plant applications ranging to more than 2000 MVA.
Explaining their testing requirements, Andrew explains, "As part of the service, and prior to commissioning of the machine following servicing, we perform pneumatic and vacuum tests on the water cooling circuit. When in use, the water circuit generally operates at 3 bar, the water-cooling circuit is in an outer casing (pressure vessel), which is filled with hydrogen at a pressure of 3.5 to 4 bar creating a positive differential".
