What is vector group? What is meant by DYN11?Why is it needed?

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.

Is This Answer Correct ?    6 Yes 14 No
