Selecting conductor for transmission line

How to calculate for transmission line conductor for a particular megawatt power?
Suppose 1000 MW power is transmitted through a particular conductor, first calculate the current for that megawatt power taking a voltage level as constant for this case we have taken 400 KV. The current comes to (1000x103)/0.732x400x1)=4018.00 amps, taking on account for double circuit (4018/2)=2009 amps; which is comparable to twin moose conductor which has 2056 amps current carrying capacity at 50oC.

Photography, in its understanding

After reading an article on photography, I realized that mega pixels of camera is not the deciding factor in opting for one of them. The resolution of the camera is only a factor that we all account for, but it has certain limitations of its own. That means that for us to view any photo on our computer screen or print it from a printer all depends on more factors like sensor, focus, steadiness of hand, stability of photo, ISO, its modes(feature available in cameras). The resolution in capturing image is important factor as it to be presented, for instant if any particular image is absorbed by the camera is of good resolution the output we see should also match for the same, what is the point in absorbing any image more than what it could be presented.

So, 5 megapixels are enough for usage. It does not mean that more than it is unaccountable but optimization of it is not possible. High megapixel mean as the systems will also take much of time to process or otherwise we need heavy ram to realize it which apparently increase the cost.

Therefore getting good specification is not considered to be wise unless otherwise utilized.

Now power substation comes in a box

Here at Bangalore, I found package substation beside road which primarily is used to reduce the size of a substation in a cubical of rated capacity of 750 kVA, which steps down 11kV to 433V. The important point that is eye caching here is that this cubical contains four circuit breaker, five mccb, instrumentation system a copper wound transformer and two grounding points. This transformer is specially manufacted to this design so as to reduce the size upto one third, manufactured by Kotsons company. The transformer is hermatically sealed without conservator, breather. The oil tank is vaccumized to reduced the space for conservator.

Hotline Maintainance

Hotline maintainance mean working on live line and maintaining the same when power is on mode. This is done by two methods that are bare hand method and hot stick method. Both method are equally important for a maintainance engineer. In bare hand method the person had wear a conductive suit that is made of microscopic stainless steel and normex material and then anyone can work on higher voltage. And hot stick method is by use of a special stick that have high insulation capacity...

Why this heart is never satisfied...

I don't know why my heart never feels satisfied, what does it mean...??? It is the dynamics of my mind, my heart, my sole or else anything else....that too I don't know...

New defination of subbornness...

"When you're out of willpower, you can call on stubbornness", quoted by Henri Matisse is rightly projected. The stubbornness is born from that point were you stake off your hand from an opposite situation that is making yourself uncomfortable. You fled always from discovering solution and taking head on to it. But why it happens so can anyone tell? Yes, everyone could with there different experience and different language vis-a-vis their expression because that is were we break down. I could even say that is an avalanche of one's syncho.

Hostel that I have seen...

Hostel, a wonderful experience of my life that came to me in the name of npti is such an experience that anyone and everyone in life should have. I was deprive of this experience because of my reasons which I did not want to express here at least, but I could really guarantee it that who had not should try to venture for it. Here rule are made to be broken, nothing is certain, anyone can be disturbed and anyone can disturb everyone at any point of time, whether it is day or night or might be mid night or early morning. Timing is one word that is searching for its definition and working is another word that means here is that work without any work. Here I mean that counter strike, girls and chatting are the main objective of working in a hostel. Unnoticed raids can occur at any point of time to your food store whether it may be modest of all food stuff like Parle-G biscuits, fruit or even can filled with water is considered a valuable store. Boy’s growling at their topmost volume and tone for a crazy match of cricket, volley ball or football. Or rather learning experience with skating and trying to stand on a pair of rolling wheel. Waiting for food in the mess or howling on each and every ball of cricket match of world cup. Making heavy and hefty comments on player like we all are sitting in parliament of cricket and pumping sms’s against those responsible for losing the match. Parties like snatching cakes and pouring cold drinks to the easiest target amongst all.
