WebAnswer / abhinav yadava. Dyn11 is vector group notation of tansformer.It means LV. winding,which is star connected (written in small letters. means LV side and vice versa)is 30 degrees lagging by HV. winding which is delta connected.In India we go for +-30. deg connection of transformer. WebNov 1, 2014 · When the load side (LT) suffers some dip the LT current try to go out of phase with HT current, so 30 degree phase shift in Dyn-11 keeps the two currents in phase when there is dip. So the vector group at the generating station is important while selecting distribution Transformer. Vector Group in Generating-Transmission-Distribution System: breakfast containers for bagels
Vector group - Wikipedia
WebThe transformer’s vector group is depending on the following factor: Removing harmonics: The star winding of the three phase transformer is used to reduce third harmonics. Parallel operations: To perform parallel … WebMay 10, 2013 · Vector Group Test of Transformer. In a 3 phase transformer, it is essential to carry out a vector group test of transformer. Proper vector grouping in a transformer is an essential criteria for parallel operation of transformers. There are several internal connections of three-phase transformer are available on the market. WebAnswer (1 of 8): Vector Group. Vector grouping is an indication of the nature of the primary & secondary connections between the three phases of a transformer, along with the phase shift (if any) of the secondary with respect to the primary. having group like Yy0, Yd1, Dyn11 etc. This relativel... breakfast cookery pdf
