Dear All, If we can use Earth wire as Neutral wire. Then what is the Different between them?Why we use neutral wire instead of earth?

The role of Neutral is to close the circuit and carry the consumer load current back to the transformer point while the earth shall carry no current in normal situations. Different systems are used to minimize the voltage difference between neutral and local earth ground. In some systems, the neutral and earth join together at the service intake (TN-C-S); in others, they run completely separately back to the transformer neutral terminal (TN-S), and in others they are kept completely separate with the house earth having its own rod and the neutral connected to earth within the distribution network (TT). In a few cases, they are combined in house wiring (TN-C), but the dangers of broken neutrals and the cost of the special cables needed to mitigate this mean that it is rarely done nowadays.

DearEr.digu As In adddition the neutral point of anelectrical supplysystem is often connected to earthground,ground and neutralare closely related. Under certain conditions, aconductorused to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in objectionable or dangerousvoltagesappearing on equipmentenclosures, so the installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground. |

hi there can you tell me where is the neutral created that us at the alternator end or at the power transformer end???? |
