Generators In Parallel

Hi! All
I just want to know that when we set a synchronoscope for paralleling two generatorswhy does it move clockwise or anticlockwise as per the speed. What actually makes it drive in either direction. Please explain about the vectors moving in either direction.

Induction Motors

Hi! Friends
Recently i tried to energise an three phase induction motor stator before assembling the rotor. Nothing abnormal happened to it. I only observed that the stator got magnetised. I failed to measure the current. I did not keep it for long for more observation. I discussed this with my colleages who were not present there, who say this is not possible and the stator winding should burn out. No one could justify the statement. What i know is if the stator is energised without the rotor then it will be like an open circuit and will draw magnetising current. To burn the winding there should be excess current more than rated which is possible only if there is no back emf in the winding or if the insulation fails due to stator core heating up due to excessive flux on saturation. Both these things are not possible as there will be back emf developed, and the core will not saturate as it is its rated voltage. Even if we look at the equivalent circuit and we eliminate the rotor resistance we remain with just stator resistance and inductance and the magnetising circuit. So the current should not be more than the no load current which the winding should carry normally.
My question is ...... am i right??? If i am wrong please correct me and let me know what exactly will happen to the winding if the stator is connected to rated supply without the rotor. I will be happy if i could get an answer in detail.
