Star connection is also known as__________a)Y-connectionb)Mesh connect...
Star connection is also known as Y-connection.
Explanation:
In electrical engineering, star connection is a type of electrical connection where the three line conductors are connected to a common point, forming a star shape. It is also known as a Y-connection due to its resemblance to the letter "Y". In a star connection, the common point is usually connected to the neutral point, and the three phase voltages are measured with respect to this neutral point.
Advantages of Star Connection:
- Easy to connect and disconnect individual loads.
- The neutral point provides a return path for unbalanced currents.
- It allows the use of a smaller neutral wire, as the neutral currents tend to cancel out.
- It provides a higher degree of safety, as the line-to-neutral voltages are lower than the line-to-line voltages.
Disadvantages of Star Connection:
- The line-to-neutral voltages are lower than the line-to-line voltages, resulting in reduced power transmission capability.
- In a star connection, the currents in the line conductors are higher than in the corresponding delta connection for the same load.
- It requires a neutral conductor, which adds complexity and cost to the system.
Conclusion:
In conclusion, star connection is also known as Y-connection in electrical engineering. It is a commonly used method of connecting three phase loads in power systems. The star connection offers advantages such as easy connection and disconnection of loads, a return path for unbalanced currents, and a higher degree of safety. However, it also has disadvantages such as reduced power transmission capability and the requirement of a neutral conductor.
