What is the d/f between DOL & star delta starter & automatic
star delta starter?
Answer Posted / suresh pulipati
In case of Star Delta starter the motor intially will run
in star connection and when 80% of rated speed picks, the
motor change over to delta connection. With this star delta
connection we are able to reduce starting current by 1/3 of
DOL starting current and starting torque also.
