Question

RRB Paper · Accepted Answer

As compared to DOL starting method the star delta starting method should have low starting current. In this method, the motor is initially connected in a star configuration, which reduces the voltage across each phase winding and hence the starting current. After a period of time, typically a few seconds, the motor is switched to a delta configuration to provide full voltage to the motor windings and allow the motor to reach full speed. In contrast, the direct-on-line (DOL) starting method connects the motor directly to the full voltage supply, which results in a high starting current. This can cause voltage drops in the supply system and can also cause mechanical stresses in the motor and driven machinery.
