Question

In a house, the wiring is commonly done by the ring system. In this system, we have a separate ring for each portion of the house.

Answer 1

1. In ring power is supplied from both ends as compared to radial
2. In case of a fault in the radial circuit the entire system goes off unlike in ring where by in case one end gets a fault the other end still keeps on supplying power
3. Compared to the radial system, the voltage drop is less along the distribution line
4. More subscribers can be installed to the system than the radial system
5. Less voltage fluctuations can be seen at client’s terminals. Voltage fluctuations in high loaded areas can be reduced using a tie line
6. Ring is very expensive n requires more materials than radial
7. Radial circuit is more economical
8. High maintenance cost
