Star delta connection find out

Question

Accepted Answer

Star delta connection is a method used to reduce the starting current of induction motors.

Star delta connection is used in three-phase induction motors.
It involves connecting the motor windings in a star configuration during starting and then switching to a delta configuration during operation.
The purpose is to reduce the starting current and minimize voltage drops in the power supply system.
It is commonly used in applications where the motor's starting current needs to be limited, such as in large motors or when the power supply capacity is limited.
Example: A 3-phase motor rated at 400V can be connected in star during starting with each winding receiving 400V/sqrt(3) voltage, and then switched to delta for normal operation.
