Installation of Electric Generator

Click For Summary

Discussion Overview

The discussion centers on the installation orientation of large electricity generators, specifically why they are commonly aligned in a north-south direction. Participants explore potential reasons for this practice, including technical, environmental, and cultural factors.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions if there is a specific reason for the north-south installation of generators, noting that many power stations follow this pattern.
  • Another participant suggests that there is no technical requirement for this orientation, citing that generators on ships can be installed in various directions.
  • A different viewpoint mentions that mounting generators east to west could lead to the Earth's magnetic field inducing voltages in the armature, which might be minimized by aligning with magnetic north.
  • One participant expresses uncertainty about whom to believe regarding the reasons for the orientation, highlighting conflicting answers.
  • Another participant notes that some hydroelectric generators are installed vertically and suggests that the orientation may relate more to gyroscopic effects rather than magnetic considerations.
  • A humorous suggestion is made that the orientation might be influenced by cultural practices such as Vaastu-Shastra or Feng-Shui.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the reasons for the north-south orientation of generators, with multiple competing views and uncertainties remaining in the discussion.

Contextual Notes

Participants express varying degrees of knowledge and experience regarding generator installation, and there are references to different types of generators and their orientations, which may not be universally applicable.

i have a burning question which i need to be answered by anyone competent here...
i want to know that...
why large Electricity generators are installed in north to south direction? i have seen many power stations & they all have generators installed in north south why are they not mounted in a direction where the exciter may point to east & turbine toward west istead of north south?
or in other words...
Is there any specific direction for the generators to be installed?
why do i see all the generators installed in north south direction?
are all the generators installed in north south direction?
if it doesn't matter then why do i see all large electricity generators installed in N/S direction?{by large i mean more then 5 MW}
did you visited any Electricity generation company ever?
in which country do u live?
if you know the answer please do post.

There is no requirement that I know of nor is there any technical reason I can think of as to them being installed that way. Generator sets are used on ships too and they change direction constantly.

If the generators are mounted east to west, then the Earth's dc magnetic field may generate voltages and currents in the armature. This would be minimized if the armature pointed to magnetic (compass) north.
 
so whom should i believe?
answer no.1?
or answer no. 2?
 
I've never paid attention to what direction they are installed. I don't think it's a question of who is right and who is wrong. Obviously generators are installed on ships. Obviously (if you are telling the truth) a lot of generators are installed in specific direction. I can also tell you that at least some hydroelectric generators are installed vertically. I DON'T think it is magnetic though. I would be inclined to believe it is more of a gyroscopic thing with the rotation of the earth. Positioned in a certain direction there would not be the drag on the bearings while the Earth rotates.

It might have something to do with Vaastu-Shastra or Feng- Shui! :biggrin:
