Delta Connection

Delta connection is a type of electrical connection used in three-phase systems. It is also known as a "Mesh connection" because of the way the circuit is formed.

Explanation:

Three-phase Systems:
In electrical power systems, three-phase systems are commonly used. These systems consist of three conductors or phases, each carrying an alternating current waveform with a phase angle of 120 degrees with respect to each other. Three-phase systems are widely used because they provide a more efficient and balanced distribution of electrical power.

Delta Connection:
In a three-phase system, the delta connection is a method of connecting the three phases. It is formed by connecting one end of each phase winding to the start of the next phase winding in a loop or triangle shape. The remaining three ends of the windings are connected to form the neutral point.

Mesh Connection:
The term "mesh connection" is used to describe the physical arrangement of the delta connection. The three-phase windings are arranged in a mesh-like structure, forming a closed loop. This arrangement resembles a mesh, hence the name "mesh connection."

Y-Connection:
The Y-connection, also known as a star connection, is another method of connecting three-phase systems. It is formed by connecting one end of each phase winding to a common point called the neutral point, and the other ends are connected to the respective phases.

Conclusion:
In summary, the Delta connection is also known as the mesh connection because the three-phase windings are arranged in a mesh-like structure. It is different from the Y-connection, which is formed by connecting the windings in a star-like shape. Therefore, the correct answer is option B - Mesh connection.

It forms like a mesh.
