Answer / iftikhar

we use star delta starter because in starting motor taking
a larg current therefor first we connect the motor in
star,because in star the phase vtg is reduced ,therefore
the starting current is also reduced

Answer / krish

in order to simplify the cumbersome circuits..... when ever
we need.

What is the differences in phase to phase voltages between star and delta connections of stator?
