      Dear Sir,

      Please help me in the following issue.

      We have received a enquiry with 63/63/0.25MVA, 80/23/??/0.42kV PT. In this we have to decide the ?? winding and the vector group connection is Ynyn0+d+syno. Whta is syn0 stands for and the customer is asking for +/-5% variation on 0.42 kV side.

      We thought of designing one 80/23/11 kV with 63MVA and 11/0.42 kV with 0.25MVA. PLease tell me whether our approach is correct or not?

      And also help us in resolving the problem.

      Regards
      Sreelatha
