Rotating electrical machines - Part 3: Specific requirements for turbine-type synchronous machines

Scope

This standard applies to three-phase turbine-type machines, having rated outputsof 10 MVA and above, used as generators - Those clauses that are appropriate apply to machines used as synchronous motors or compensators - This standard supplements the basic requirements for rotating machines given in IEC Publication 34-1 - This standard does not apply to those machines which are excluded from the scope of IEC Publication 34-1 - Section Two of this standard gives the specific requirements common to all turbine-type machines - Section Three of this standard specifies further requirement for air-cooled turbine-type machines - Section four of this standard specifies additional requirements for hydrogen or liquid cooled turbine-type machines - Section five of this standard gives the specific requirements for turbine-type machines driven by combustion gas-turbines - Specific requirements for both rotating and static exciters are under consideration and it is intended that these will form Section Six of Publication 34-3 - Tests for determining the efficiency and the quantities of synchronous machines are dealt with in publications 34-2 and 34-4 respectively
