Comparison between Star (Y) and Delta (Δ) Connections

In this short after we will discuss about the difference between star coupling and triangle. Before going any further, let us refresh about the star connection and triangle connection.

In this short after we will discuss about the difference between star coupling and triangle. Before going any further, let us refresh about the star connection and triangle connection.

Between three terminals A, B and C, we can connect three resistors in the following two methods.

In the framework of stars , one end of each resistor is connected to a point (which is called a star point) and the other three terminals are connected to A, B and C. As it resembles a star, Connection type is called star coupling.

On the other hand, in the delta connection , the three resistors are connected end to end so as to form a triangular or triangular shape.

In some complex electrical circuits, the calculation of the total resistance will become simpler if it is in star coupling.

In some other circuits, the calculation of the resistance will become simpler if it is coupled triangle.

Between three terminals A, B and C, we can connect three resistors in the following two methods. In the framework of stars (1), one end of each resistor is connected to a point (which is called a star point) and the other three terminals are connected to A, B and C. As it resembles a star, Connection type is called star coupling. On the other hand, in the delta connection (2), the three resistors are connected end to end so as to form a triangular or triangular shape. In some complex electrical circuits, the calculation of the total resistance will become simpler if it is in star coupling. In some other circuits, the calculation of the resistance will become simpler if it is coupled triangle. Comparison of star coupling and triangle coupling Delta-connected loads dissipate three times more power than when connected star-shaped to the same power supply. For the same power, the phase currents must be the same for both delta and star connections (from Power P = 3IP2 RP). Thus, the line current in the delta-connected system is greater than the line current in the corresponding star-connected system

Comparison of star coupling and triangle coupling

Delta-connected loads dissipate three times more power than when connected star-shaped to the same power supply.
