Three phase alternators are connected in star connection
why?

Answer Posted / binod pradhan

2-in star connection the phase voltage is low than the line voltage,so it required less no of turn. 3-low insulation required as phase voltage is low. 4-1 neutral point available in star connection. 5-unbalance current flowing in the three phase circuit, neutral is having a vital role.It will take the unbalance current through to the ground.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
