Answer Posted / shraddha
I read a number of answers but nobody has cleared about the
leading and lagging thing. In case of Dyn11, 11 indicates 11
o'clock i.e. a displacement of 30 degrees between HV and LV.
Now in this case, is HV leads LV by 30 degrees or vice
versa and how can one find out that in any of the cases.

we have two motors 1250kW,6.6kV to be coupled on the same shaft ,so please provide assistance for their synchronisation.
Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
