As such, there would be negligible current through the neutral point, which can be tied to ground. Each phase, therefore, couples with each other phase, and the voltages cancel out. The second coils are then all tied together to form the neutral, and the phases are connected to the primary coils. In all cases, six or nine winding, the first coil on each zigzag winding core is connected contrariwise to the second coil on the next core. As with the conventional delta or wye winding configuration three-phase transformer, a standard, stand-alone transformer containing only six windings on three cores can also be used in zigzag winding connection, such transformer sometimes being referred to as a zigzag bank. ![]() Nine-winding, three-phase transformers typically have three primaries and six identical secondary windings, which can be used in zigzag winding connection as pictured. ![]()
