A star-delta starter is an electrical motor starting device that reduces the starting current and torque of the motor.

• It consists of a contactor, overload relay, and timer.

• During starting, the motor is connected in star configuration to reduce the voltage across each winding.

• After a set time, the motor is switched to delta configuration for normal operation.

• It is used for large motors to prevent damage to the motor and power supply.

• It is commonly used in industries such as oi...read more
