## What is a Star connection?

Star Connection (Y) System is also known as Three Phase Four Wire System (3-Phase 4 Wire) and it is the most preferred system for AC power distribution while for transmission.
In Star (also denoted by Y) system of interconnection, the starting ends or finishing ends (similar ends) of three coils are connected together to form the neutral point. Star Connection is obtained by connecting together similar ends of the three coils, either “Starting” or “Finishing”. The other ends are joined to the line wires. The common point is called the neutral or Star Point, which is represented by N.

## How to Calculate Star to Delta transformation?

Star to Delta transformation calculator uses Delta Impedance 1 = Star Impedance A+Star Impedance B+((Star Impedance A*Star Impedance B)/Star Impedance C) to calculate the Delta Impedance 1, The Star to Delta transformation formula is defined as the transformation of impedance connected in a star connection to delta connection.
