Hello CB TRIPATHI
Welcome to the forum You will not save energy by replacing a DOL starter with a star delta starter. The start current in star will be less than the start current in delta, but the machine will take longer to start. The total energy consumed will be about the same provided that the motor can get to full speed in star. Best regards, -------------------- Mark Empson administrator
