๐ Star Connection vs ๐บ Delta Connection
Star Connection (Y):
- Each phase winding is connected to a common neutral point.
- Phase voltage = Line voltage รท โ3.
- Used for starting motors with reduced voltage and current.
- Suitable for long-distance transmission due to lower current.
Delta Connection (ฮ):
- Windings are connected end-to-end forming a closed loop.
- Phase voltage = Line voltage.
- Used for running motors at full load with high torque.
- Common in short-distance distribution and heavy-duty motors.
โก In short: Star โ lower current, safe starting; Delta โ higher power, efficient running.
