Direct On Line( DOL) starter takeS Full load current
Ist=Ifl But STAR/DELTA starter which during starting of
motor , connected terminals with STAR which limits Ist
=Ifl/1.732*Ifl. Thus starting current can keep with in
limit.

Answer / erharisheee51

DOL TAKES FULL LOAD CURRENT WHERE AS STAR DELTA STARTER LIMITS THE STARTING CURRENT BY FIRST STARTS AT STAR THEN CONVERT IN TO DELTA , WHER EIN STAR IT LIMITS BY I/1.732, IN THE PLACE OF STAR DELTS STARTER WE SHOULD NOT USE DOL- DIRECT ON LINE STARTER , WHICH IMMEDIETLY STARTS AT FULL SPEED.
