Cables

This is a basic problem in power distribution. If you do not have the experience to handle this problem, you need to hire an engineer who does.

Is this a general interest question, a homework question or are you a clueless electrical consultant (or similar) trying to get we professionals to give you the answer (ie- doing your job for you, which I might point out is a job you are not qualified to do if you are asking these questions?

Could you please provide more information, and I will reserve judgment until I get an answer, as there really is no way to tell which group you are in.

From a 11KV line we must distribute the power to the industries according to the load..how do we do this???whats the procedure?? the area of the land is given..what are the parameters required and the calculations???

Hi guys! I see what you're getting at here... so *I* will try to answer... I did a little bit of work on my MS in power (never finished).

Um... lemme see...

Well, you need to know the like is 11kV so that's good.

Since you want to distribute according to load, you need to know the load(s).

Area of land? You don't need AREA I don't think - you need the length to each point you want to go to. Definitely need line length.

Then you should take into account the line resistive and inductivev, parasitic capacitance, the way the line is set up - is it transposed (typically assume yes), what about grounding scheme? Might need to include the earth resistivity, depending- which is usually an estimated number.

What kind of like? Is it a single phase? 3 phase?

Or alternative, there are lots of tables... there might be a table that tells you exactly what you want to know.

That's what I remember having to consider off the top of my head.

How'd I do guys?

From the original post

From a 11KV line we must distribute the power to the industries according to the load

Little detailed information is actually provided, so this statement could mean taking an 11kV line and then having to step it down to the local supply voltage (such as 400V 3 phase). In this case, 11kV/400V transformers or similar will be needed, possibly multiple, possibly switching yards, possibly even a full substation or more depending on load size, how far the loads are away from each other, etc.

Even a broad answer cannot be given, such as "well assume 5 sq m for every 100kW delivered".

Like most things in life there is no single easy set of answers, if there were I wouldn't have spent almost 7 years at university getting my engineering qualifications to work in the power industry.

I still think this is a homework question, in which case a general explanation on power distribution can be found on the internet easier than trying to find CR4 for the first time.
