Three phase systems are extremely common in industrial and commercial settings. Although these systems may seem intimidating at first a walkthrough on 3 phase wiring for dummies will help clarify the whole situation.

Y connection 3 phase motor. 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 delta connection is generally used. Phasor diagram showing phase and line voltages. Unlike delta connection wye connected systems carry a fourth neutral conductor often grounded but sometimes left floating ungrounded wye system. In star connection the phase voltage is low as 13 of the line voltage. In delta connection motor receives highest power output. They can also be found in large residential complexes and appliances requiring a large amount of power.
In delta connection the phase voltage is equal to the line voltage hence it needs more number of turns which increase the total cost. Let us consider the system of the figure 4 which is balanced y y three phase four wire system if the source voltages are given by 1. For example the wye connection requires fewer turns than the delta connection 17322 to achieve the same electrical characteristics. These results may also be obtained graphically from the phasor diagram shown in figure 3. This video is 3 phase motor connection proper star and delta connection full step by step a to z crimping tools amazon httpsamznto2akjmjo youtube playlist video. Often the connection will depend on the manufacturing process.
Although the wye and delta connection diagrams are quite simple the actual motor windings are far more complex. Different regions may use different voltages. Therefore it needs a low number of turns hence saving in copper. This video shows changes the induction motor wiring from star connection to delta connection. The 3 phase impel induction motor can be connected in delta connection and star y connection. Initially we explored the idea of three phase power systems by connecting three voltage sources together in what is commonly known as the y or star configuration.
Star connection line and phase currents. This configuration of voltage sources is characterized by a common connection point joining one side of each source. Wye y connection also known as y connection is a three phase circuit in which all the three loads are connected at a single neutral point.
