because,in 6.6kv we reqiure high starting torque so that we use star connection and also line voltage=root of 3 *phase volage
and also in this motor we connect more load so current drawn by this motor is high so we reduce by star connection

please write motor, transformer, Generator setting, fault level calculation of Tr.etc
