Webnormally 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. WebJan 30, 2024 · A vector group is the International Electrotechnical Commission (IEC) method of categorizing the high voltage (HV) windings and low voltage (LV) winding configurations of three-phase transformers. The vector group designation indicates the windings configurations and the difference in phase angle between them.
