⏯️Star and Delta Connection of Three Phases Motor
▶️What is Star & delta connection?
A Star Connection is a 4 – wire connection (4th wire is optional in some cases) A Delta Connection is a 3 – wire connection. Two types of Star Connection systems are possible: 4 – wire 3 – phase system and 3 – wire 3 phase system. In Delta Connection, only 3 – wire 3 phase system is possible.
▶️ Which is better Star or delta connection?
Star connection is preferred for long distance transmission and distribution as it requires low insulation and has a Neutral which helps to balance the circuit. Delta connection is preferred for shorter distance transmission and distribution as it requires more insulation and has the problems of unbalanced currents.
