Electrical Installation

3.1. Distribution Network in electrical systaem

 
The distribution network  is the final stage of the electrical power system, delivering electricity from substations to consumers.

           Types of Distribution Systems  
1. Radial System  
   - Power flows in one direction from the substation to consumers.  
   - Simple and cost-effective but prone to outages if a fault occurs.  

2. Ring Main System 
   - Power flows in a loop, ensuring continuous supply even if one section fails.  
   - Used in urban areas for reliability.  

3. Interconnected System
   - Multiple substations and feeders are connected, allowing flexible power distribution.  
   - Provides redundancy and minimizes outages.  

           Components of a Distribution Network
- Substations:   Step down high-voltage power for distribution.  
- Transformers:  Adjust voltage levels for different consumer needs.  
- Distribution Lines:  Overhead or underground cables carrying electricity.  
- Protective Devices:  Circuit breakers and fuses to prevent overloads.
