Question: Which of the following dc distribution system is the simplest and lowest in first cost?
A Radial system
B Ring system
C Interconnected system
D None of the above
Answer: Radial system
| Aspect |
Description |
| Name of simple dc distribution system |
Radial system |
| Configuration |
Single-path distribution system with one source and multiple load points. |
| Operation |
Power flows from the source to the load points in a single direction, typically downstream. |
| Common Applications |
· Residential neighborhoods.
· Small to medium-sized industrial or commercial areas. |
| Reliability |
Relatively simple and reliable for small to medium-sized distribution networks. |
| Advantages |
· Simplicity and low initial cost.
· Easy to design, install and maintain.
· Suitable for linear networks. |
| Disadvantages |
· Limited redundancy, making it vulnerable to outages if the source or feeder fails.
· Not well-suited for critical applications requiring high reliability. |
| Example |
Many urban and suburban electrical distribution networks use radial systems. |
