Answer / baljinder singh
There is starter used for A.C. motor, according to
rating,the rating and starter used for A.C. motor give as
follow-
1 hp to 5 hp ----- only D.O.L. starter
6 hp to 20 hp ----- star-delta starter
more than 20 hp ---- auto transformer starter

Starter selection can be taken in accordance with the Motor HP rating.ie,
1. For 1HP - 5HP Motor :- DOL Starter can be used.
2. For 5HP - 20HP Motor :- Star Delta Starter can be used.
3. For 20 HP & above :- Auto Transformer Stater can be used.

For a 25 HP Induction motor one should use the star delta
starter. During the starting the motor draws 5 to 7 times
its normal current rating due to high inertia of its
armature. In the star circuit the Il=Tph as a result the
current is high. Its like moving a startionary object from
its position we require high force.
Pls add more.

UPTO 5HP DOL STARTERS USED ABOVE 5 HP STAR DELTA SARTER IS
USED BECUASE IT LIMIT THE STARTING CURENT

Answer / umesh joshi
Star Delta starter should ba used, because motor draws high
current in starting so we used motor should be in star and
after sometimes it is in delta so that that motor is ni
safe position
