Electrical Engineering
Chapter 1 : A.C. Fundamentals
Topic : Comparison between star and Delta connection

Comparison between
star and Delta connection :-

  1. In
    star connection similar ends are joined together where as in delta
    connection dissimilar ends are joined together.
  2. In
    case of star connection, line voltage is √3 phase voltage
    whereas in case of delta connection line voltage is equal to phase
    voltage.
  3. In
    case of star connection line current is equal to phase current whereas
    in delta connection line current is equal to √3 phase current.
  4. In
    case of star connection it is possible to carry the neutral wire to the
    load whereas in delta connection it is not possible.
  5. All
    distribution transformers are Delta/Star connected whereas power
    transformer are Delta/Delta connected.
