dol starter doesnt make any change in the starting torque.

Answer / yvb

Absolutely there is no specific advantage if you are a
small user. for heavy industries it is advantageous coz of
less parts(contactors & timers) comparitive to Y/D
starter.for industries that dip when we start a motor using
DOL will take their grid or CPP ,where as for small users
they may not have such facility. so the flour mill users
will use Y/D stater to avoid sudden load on supply lines.
