But what do we mean by star also known as Wye and delta also known as Mesh when dealing with three-phase transformer connections. In Delta also denoted by Δ system of interconnection the starting ends of the three phases or coils are connected to the finishing ends of the coil. Symbols are generally used on a three phase transformer to indicate the type or types of connections used with upper case Y for star connected D for delta connected and Z for interconnected star primary windings with lower case y d and z for their respective secondaries.
Delta or Mesh Connection Δ System is also known as Three Phase Three Wire System 3-Phase 3 Wire and it is the most preferred system for AC power transmission while for distribution Star connection is generally used. High Leg Delta also known as Power Leg or Wild Leg is a three phase four wire power distribution system used in commercial buildings in North America especially in rural and older installations.
