What Things and Clearance SHOULD Consider to Prepare a Layout of High Tension (HT) (33KV/11KV) Substation? A Layout of 33KV Outdoor Substation.

Special points should consider to prepare a Layout of 33KV Substation with Four Pole Gantry Structure:

High tension (HT) substation is an important part to draw high power from transmission line to end user. For a good, flawless operation and maintenance, following important points must keep in mind while laying out an HT substation.

1. By considering growing load, the location of substation should be designated in an extendable location.

2. Location should be easy transportation competence for transformer handling and if the replacement of transformer is prerequisite.

3. As far as possible, substation location should be in the center of load.

4. Enough space should be well-thought-out between the substation element for proper operation and maintenance.

5. Safety arrangement like firefighting equipment should be provide.

6. Should preserve the proper clearance between the HT elements to ground.

7. Should consider the low capital cost and high reliable material for structure.

8. Substation location should be free from pollution area because of polluted air can harm the structures.
