Answer / sameer saxena

to reduce the complexcity of circuit electrical engineers used star delta conversion for solving the circuit euations.

Answer / shashank

it is to reduse high starting current. it applied to high
cap motor like Above 10 hp. it means motor should run star
connection to reduse the starting current after she running
in delta in half of normal currunt.

Answer / s.sakthivel perambalur

with neutral power supply is known is as star, with out
neutral power supply is known as delta,its applied for
transformer and motor,and use for to change the voltage with
out changing of frequency,and to limit the starting current
in motor
