scc of synchronous generator

Open-Circuit Characteristic is the graph of generated voltage against field current with the terminals open-circuited and running at synchronous speed.

Short-Circuit Characteristic is the graph of stator current against field current with the terminals short-circuited.

Question:
To obtain the SCC plot, do we need to run the generator at synchronous speed?

Thanks.
 

occ generator

of course my brother...
when your synchronous machine is short circuited but running at synchronous you will get the nominal current at full load of machine... but the voltage will be less than nominal...
