Star Delta is Used only in case of Delta connected Ind motor... And star connection reduce the starting current and starting torque to 1/3 of its original value...

[@cookwithpanda6199]

Magnetostriction is the reason of humming sound in transformer... Magnetostriction means change in dimensions of core material due to magnetic field... and is reduced by tightning of Core and proper stacking of cores...

[@cookwithpanda6199]

change in length of Dimensions due to magnetic field..
