Answer Posted / gunasekaran
normally Dyn11 vector group using at distribution
system.because GT are YNd1 for neutralizing the load angle
between 11 and 1. we use Dyn1 at distribution system we r
using GT are YNd11. in some industries 6 pulse electric
drives are using due to this 5thharmonics will generate if
we use Dyn1 it will be suppress the 5th harmonics.
