related to electrical engineer from india

Hi Guest,

Please read the link below and then if you have any further doubts post it for further clarification.

A finger on the pulse to be sure. GA V.I.

It struck me that perhaps a picture of a physical grid of some sort would help understand the use of the word in this instance. Like fence wire or window screen cut out to the shape of continents and laid on a globe of the world.

Hi CJcGill,

Please see the link . The picture of the Indian Electricity grid is very much there in the link . That is self explanatory with map of India.

I suppose that I should clarify my previous comment.

The intent was to have the questioner refresh himself on how the word "grid" might apply to electricity.

A fencing or graph-paper type of picture usually comes to mind upon hearing that word, nicely evenly spaced squares. Being very logically minded a student might not comprehend the use of 'grid' from the visual of that map, with few parallel lines and no 'dots' at the crossing points to indicate where interconnection exists.

Many electrical students have learned that electrical circuits are very much like plumbing or tree roots. They have studied systems that do not interconnect once they have extended beyond the common source (panel).

To expect that the word "grid" would be comprehended without an understandable explanation simply from a map with lines going every which way might fail in the intended communication.

Also, the Indian 'grid' is missing many of the interconnections. It has islands of locally generated power not interconnected. Even the concept of 'grid' in the distribution within those islands could use some explanation.

Perhaps beginning with an understandable visual of 3 or 4 diesel generators feeding one large main panel. They can understand that interconnection. Then extend that by visualizing another business nearby with the same setup, and explain that with the right equipment, these two businesses can link their generator banks together to form a larger bank of generators.

Thus begins a 'grid' at it's infancy, with the advantages of back-up availability etc.

Did I communicate my idea better this time?

Hello CJMcGill:

I understood both times but that maybe because I grew up automatically it seems, knowing what a 'grid' was. Perhaps someone why has not had an interest in Electricity before and, in truth I think the OP is pretty young. Said he was an Electrical Engineer perhaps because he thought (wrongly) that he would not be welcome on the site as a student?

There was nothing wrong with your explanations. But I can see how the word 'grid' can be misleading. That is why I likened it to a railway. I think it has more similarities.

But, it was kind of you to come back and explain your ideas further. There is nothing worse that someone saying something and automatically assuming you know? On here it is not too bad as most are honest and admit to there lack of knowledge. And poster understand we all have our own level and 'expertise' if you like, in any subject?

I hope the original poster comes back and has not been scared away.

Take care and have a wonderful holiday!

Hello Guest,

Now I mean no offence OK?

But I think you may mean:

"you are an "Electrical Engineering Student"? Not an "Electrical Engineer".

It is called a grid because if viewed from above, from a plane for instance the power lines form a kind of 'grid'.

It is 'interconnected' because a grid of wires has been laid to each Factory, Hospital and home in the land. It is interconnected to allow the distribution of power (Electricity) as and when it is needed . Some Factories close for the weekend. But some of the power they would have used gets redirected to the workers homes as they will be using the electricity there rather than 'at work'.

And, like a railway system, when some areas need more power at night, or when it is cold, that power can be directed via Electricity Substations to yet smaller substations and finally to the house where it is needed.

This is very basic Knowledge here Guest.

The energy distribution is a private business in the UK for instance, and the companies got together years ago to decide who shall supply power for the whole UK. When one power supplier needs more then, it usually happens automatically, that the power is redirected around and along the grid to where it is needed. And the seller will be paid by the buyer in future months or years.

It is very similar to a countries railways systems. The trains can be looked on as the power going along the lines and, when the power has to be redirected to another area, it is like when a train changes direction as it goes though 'points', Those railway points are the cable relays and substations in the Electrical world.

I hope this helps. I would advise you to be truthful when requesting help from people. That way you get to know each other and become friends on-line and can swap knowledge. But I think you may have a lot of learning to do before you start work as an Electrical Engineer, is that right?............There is nothing 'wrong in not knowing. A person can never know everything. But you should be honest when asking for help OK?

Take care and good luck at school.

If you were an Electrical Engineer you would have the answers to all your questions.

Hello guest,

Nice to hear you are electrical engineer, but sounds not pretty good for having NO basic understanding on all of your question which is related for electrical engineering. I would suggest next time Never introduce your self as an electrical engineer as you are asking a question which are related on your profession or degree, it's look funny however you can go ahead and most welcome to ask with out mentioning you are an electrical engineer, we considered or I considered not all of things in our individual field we know and we encountered so the best tools is "ASK" psssssst! don't tell everyone you are an electrical engineer.

Kind regards

And who might be an illegal resident worldwide?

milo

Hello Alan Pocrass:

Eligibility: The contest is open to all legal residents worldwide who are 18 years of age or older and work within the design engineering industry.

You wrote this. I suggest you redraft it pretty damn quick.

If you are trying help or advise, this is not the kind of sentence anyone would like to read. I understand you probably meant 'Legally', but it is a sloppy excuse for a letter.

For a more understandable letter it may pay you to open your paragraphs a little. It is all too cramped.

No offence intended..........

Have a great new year......................
