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.
