State the condition for selecting site for distribution substation. 

1 Answer

Answer :

Following condition should be considered while selecting site for distribution sub-station:-

 1. Near load center :

 Sub-station should be located near load center to reduce cost of Transmission and distribution lines and to reduce losses in it.

2. Easy access for transmission Line :

 There should be easy access for incoming and outgoing line.

3. Easy access towards sub-station :-

 There should be easy access towards sub-station for transportation of equipments and manpower etc.

4. Space(Land ) available :

 The land proposed for a substation should be normally level and open from all sides & sufficient land should be available for installation of sub-station and future expansion.

5. Atmospheric conditions :

 Atmospheric condition in the area of sub-station should be clean and dry also There should be less atmospheric pollution.

6. Cost of land :

 Cost of land should be less to reduce capital cost of sub-station.

7. Municipal restriction :

 Where municipal restriction will not take any objection for required type building of sub-station.

8. Staff amenities :

 The site should be such that essential amenities must be available to staff like residential quarters, drinking water, school, hospital, public transportation, communication.

9. Bearing capacity of land (Hard land ):

 To reduce construction cost of building and for better foundation of equipment’s land should have high bearing capacity.

10. Area free from earthquake :

 To avoid damage to sub-station area should be free earth quake.
