See Chinese contents: GB/T 20140-2016 GB/T 20140-2016: Measurement method and evaluation criteria of dynamic characteristic and vibration on stator end windings of cylindrical synchronous generators
This Standard specifies the measurement method and evaluation criteria of dynamic characteristic and vibration on stator end windings of cylindrical synchronous generators. This Standard applies to 4-pole cylindrical synchronous generators of rated rotational speed 1 500 r/min and 1 800 r/min and 2-pole cylindrical synchronous generators of rated rotational speed 3 000 r/min and 3 600 r/min, with a rated power 200 MW and above.
