What is Star Connections,Voltage ,Current and Power in Star connections,Summary of Star connections,Uses of Star connections,
Star Connection Star Connections is a method of connecting pohyphase circuit is such a way that one end of each phase line is connected to a common neutral point that may be connected to the earth as protection against lighting or to a wire to which all the other neutral points of the system are connected. It is also known as three phase four wire system.It is denoted by Y.It is the most preferred system for AC power distribution. If we connect the balance load across three phase voltage system in parallel,then the three currents will be flow in neutral and their quantities will be same .The angle between them is 120ยบ.So we can say That the sum of all currents is zero. ...
