Pdf star delta stater
The document discusses star and delta connections for three-phase power systems. In a delta connection, the line voltage equals the phase voltage and the line current is lower than the phase current. In a star connection, the phase voltage is lower than the line voltage and the line current equals the phase current. The document also mentions converting between delta and star connections, and using a star-delta starter to gradually apply voltage in a motor.
