Neutral Path

I have the feeling nobody understands your question

its not pain make it paid

No, still makes no sense.

When writing on a foreign language the most common mistake is to do a literal translation of each separate word into the target language. If both languages share the same roots (Latin, Germanic. etc), the word-by-word translation may make some sense. If not, it will yield an unintelligible jargon. When writing in alien languages, a good advise is to google for texts about similar matters. This will allow you to understand how to put your ideas in words someone else can understand.

Sorry, old bean. Don't understand your banter.

Revised using punctuation "Why should we have neutral path. Is their any return current when short circuit happen? If that is the case, that will be loss for us. Know bcoz we already pain for that unit while receiving power.

This last portion of the sentence needs further explanation. What is you basic question?

My K security lit up also. Bad place to go.

How about this:

Why would our facility require neutral bonding? Is there any return current on the neutral if during a phase to ground fault? If a bonded neutral is required and we have to have our system re-engineered, my company would lose money. Due in part to the fact that we already paid for the installation of a ungrounded system when we had the service connected.

It's a reach, I know.

OP still hasn't replied yet, either.

In a perfectly balanced 3 phase circuit the neutral path has zero net current. In the real world that does not really happen. The neutral point (where the path leads to) is the common connection of three transformers that are 120 degrees out of phase with each other. If your loads are single phase, then you are taking the power from the secondary coil of only 1 of the three transformers. To balance the use of the power, you should have 1/3 of your load on each of the three transformers.

There are many ways to have a short circuit. Most circuit breakers protect the wiring from excessive heat by interrupting the path from a "hot" wire to where ever the current wants to go. And, a short circuit does not get to use very much power if the circuit is properly designed. If you have high neutral current, it is most likely due to an unbalanced load. You only pay for the power from the "hot" side. Neutral is simply a point of reference.

Are you referring to single phase or three phase or both single phase and three phase?

What ever phase it is you only pay for what you get from the hot leg(s), not the neutral.

Mr. Nagaraj, Think in another way! Even without any short circuit, the phase current you receive for your electrical installation is returning back to the source through the neutral. That is, let us say, if you have a 10A single phase connection at your house, the 10A you draw thro the phase wire is instantly returned back to the source through the neutral. That is, you took 10A thro the phase wire and you returned the same 10A through the neutral wire, at the same instant. The why should you pay the electricity board?

I think the o.p. sentence could be as following:

"Why should we have [neutral] a grounding path as the return current [to utility] when short circuit happens, since in this case it will be a loss for us because we already paid for that while receiving power."

That means: why to return the short circuit current to utility since we already paid for it?

That is the difference between "power" and "current". You don't pay for current but for power. Even in a short-circuit case you get power from utility-and in time you receive energy,

by multiplying power by time. Only if you would produce your own energy by transforming other energy as gas, oil, coal, wind, water fall, sunshine or other into electricity then you could supply energy back to the utility.

ahh, yes. That makes more sense and is in keeping with some questions here on CR4 just like it.
