Why Do We Use Star Connection On Transmission And Distribution On Delta?
The star connection is mainly required for power transmission networks
for longer distances, while the Delta connection is mainly used in distribution networks and is used for shorter distances.
For long-distance transmission and distribution, a star connection is preferable because it requires little insulation and has a neutral conductor that helps balance the circuit.
Delta connections require more insulation and cause unbalanced power problems. They are therefore preferred for transmission and distribution over shorter distances.
