Star Connection vs Delta Connection - Difference between Star and Delta Connection
As we know that Star & Delta Connection is only possible in 3 phase system, so in our domestic system it is not possible, because generally all house hold electrical equipment are designed with single phase supply. In a three phase circuit, there are two types of connections. One is known as Star Connection, and the other one is Delta Connection.
omparison between Star and Delta Connections
We mostly use the terms star and delta in electrical systems while discussing three phase AC circuits and electric motors. Below is a given table which compares both Star and delta connections which shows the exact difference between Star (Y) and Delta (Δ) Connections.
Star Connection:
Star connection “Y” is obtained by joining together similar ends of coils either “starting” or finishing. The other ends are joined to the line wires. The common point is called the Neutral or Star Point. This three-phase, 4-wires system is used in power distribution, transformers and small scale domestic and residential applications.
Delta Connection
Delta or Mesh Connection “Δ” is obtained by connecting the starting end of the first coil to the finishing end of the second coil and so on (for all three coils) which forms like a closed loop or mesh circuit. This three-phase, 3-wires system is used in power transmission, transformers, and large scale industrial and commercial applications.
In both systems, the Voltage between two phases (Line to Line) is known as Line Voltage, while the voltage between Phase to Neutral (Line to Neutral) is known as Phase voltage. The voltage between any line (or phase) and Neutral is single phase while the voltage between all three lines (or phases) is known as three phase voltage. Keep in mind that the power in both systems are always equal and the same as it is the game of different levels of voltages and currents only used in different systems based on the requirement.
