what is phase and neutral?

Question

phase carries positive charge neutral carries negative.

what is this phase and neutral mean. The power generation in power station is generally ac. why it need two wire()phase and neutral)? whether it is possible to generate in single wire?

In dc what is +ve and what is -ve charge? what is it mean?

Answer 1

In order to use the generator more effectively a phase is spli into three namely R,Y,B. each 120 phase shift from other.
The power generated is transmitted by 3phase-3 wire system considering economy.
In distribution side there are low consumers for whom Single phase power feeding is inhalf. For them a seperate cnductor called neutral is provided ad a return path.
Neutral also helps to balance the load during unbalaced loading/fault.
Neutral is a point that is taken from the meeting point of three phases and is usually grounded to ensure balanced loading.

In dc +ve side is something where excess protonsr present and flow towards otherside and -ve side contains full of electrons which flow towards +ve side.

Answer 2

n terms of power distribution, phase (active) carries a alternating current, which neutral carries a returning current back to the power grid.

to understand this concept you must be aware that for current to flow there must be a potential voltage between 2 points. whether it is AC or DC. in the case of power generation, there is a potential voltage between the phase (active) line and neutral line. there is also a potential voltage between the active line and earth (which acts as a giant neutral conductor). this is why you can be electricuted if you contact the active wire and earth at the same time.

depending on how u look at it, its not possible to produce electricity over a 'single' wire because there would be no potential voltage.

for example, electric trains get power from a single over head line. the steel tracks that the train rides on act as a conductor form a return path for electricity back to the power grid, and thus there is a potential voltage between the overhead wire and the track.

in dc, +ve and -ve referece to positive charge (+ve charge) and negative (-ve charge).

Answer 4

nichola tesla would answer this very plainly, you have a yin and yang expressed as a current of opposing dna strands, and that sort of acts like a feedback mechanism on the nature of the message inside the copper atoms of the 2 wires.

Answer 5

M. Vinoth Kumar says "Neutral ....... is usually grounded to ensure balanced loading."

Who on earth told you that?

"Grounding", as you call it, has nothing whatsoever to do with balancing the load on the phases.

Answer 6

iam not sure
phase
neutral
