IEC 60034-3-2007 Rotating electrical machines - Part 3: Specific requirements for synchronous generators driven by steam turbines or combustion gas turbines

Language: English, FrenchInternational Standard IEC 60034-3 has been prepared by IEC Technical Committee 2: Rotating machinery.
This sixth edition cancels and replaces the fifth edition published in 2005. This edition constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows:
• the contents is now restricted to synchronous generators driven by steam turbines or combustion gas turbines, but covers as well cylindrical rotor and salient-pole generators;
• synchronous motors have been taken out of the scope of part 3.Scope
This part of IEC 60034 applies to three-phase synchronous generators, having rated outputs of 10 MVA and above driven by steam turbines or combustion gas turbines. It supplements the basic requirements for rotating machines given in IEC 60034-1.
Common requirements are prescribed together with specific requirements for air, for hydrogen or for liquid cooled synchronous generators.
This part of IEC 60034 also gives the precautions to be taken when using hydrogen cooled generators including:
– rotating exciters driven by synchronous generators;
– auxiliary equipment needed for operating the generators;
– parts of the building where hydrogen might accumulate.
