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. |
