    Abstract - (Show below) - (Hide below)

    Pertains to three-phase cylindrical rotor synchronous machines, having rated outputs of 10 MVA (or MW) and above. It supplements the basic requirements for rotating machines given in IEC 60034-1. The special requirements of machines continuously fed by inverters are not covered by this standard.
