Dear Rasam, Delta; line voltage is equal to phase voltage, while line current is equal to phase current times the square root of 3. Wye; line voltage is equal to phase voltage times the square root of 3, while line current is equal to phase current. The conductors connected to the three points of a three-phase source or load are called lines.The three components comprising a three-phase source or load are called phases.
