Comparison Between Star and Delta Connection
Star Connection | Delta Connection |
---|---|
Also called as ‘ Y’ or ‘Wye’ connection | Also called as Mesh Connection. |
It is a 4- wire connection | It is a 3- wire connection |
The common point in star connection is called Neutral or star point. | There is no neutral point in delta connection. |
Line Voltage is root three times phase voltage i.e. VL=√3 VP | Line Voltage is equal to the phase voltage i.e. VL=VP |
Line current is equal to the phase current i.e. IL=IP | Line current is root three times phase current i.e. IL=√3 IP |
Star connection is used for long distances | Delta connection is used for short distances. |
Star and Delta Connection
Star and delta connections are the types of three-phase circuits. Electric circuits are divided into Single-phase AC circuits and Three-phase AC circuits. A Single-phase system consists of two conductors, one is called phase (through which current flows) and the other is called neutral ( acts as a return way to complete the circuit). A Three-phase system consists of three conductors, which is the more economical way to transmit power than a single-phase system. In electrical circuit analysis there are certain type of complex circuits that have resistances connected in either series or parallel. These complex arrangements are usually connected in the T, Y, Delta or pi connections. Among these star and delta are some common types of connection.
