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