1 Answer

Answer :

Following factors are to be considered while designing the Feeder: 


1) Current carrying capacity of conductor:- Conductor should have high current carrying capacity. While voltage drop consideration is relatively not so important It is because voltage drop in feeder can be adjusted with the help of tapings of distribution transformer manually or by using AVR (Automatic Voltage Regulator) 


2) Need: Depending upon application design of distribution system should be selected i.e. whether continuity of supply is important or not so important 

 Example: 1) Use Radial distribution system in rural area 2) Use Ring main distribution system in urban area 3) Use Grid distribution system where continuity of supply is important. e.g. Supply to - electric traction, TV broadcasting centre, AIR, telephone exchange, major hospitals, important government buildings and major industries 


3) Availability of power: It should be available whenever needed 


4) Maintenance: It should be low, easy, less costly & less time consuming. 


5) Power Factor of load should be consider while designing
