The earth conductor is not normally used for communications, but the line conductors frequently are. Often 'communications' has nothing to do with telephone conversations, but more to do with data transmission - usually related to protective systems for the lines themselves. To prevent these communications signals from straying to other parts of the electrical transmission/distribution network, the ends of the conductors used for this purpose are fitted with inductors which offer a high impedance to the high-frequency communications signals, effectively blocking the signals from going further into the network.

When charge are able to flow directly from the circuit into Earth a ciruit electrically?

That is what the Earth wire does. Normally it does not carry current but it has this important safety function.


Can you connect a 6mm earth wire to a 2.5 mm earth wire?

A 6 mm earth wire can be used to replace a 2.5 mm earth wire, but if there is an existing 6 mm earth wire it must be 6 mm all the way to the earth, and not replaced by a smaller wire between it and the earth connection.


Is instead of neutral wire can you ground it by putting the wire in to earth if yes then why is extra wire used for neutral by eleminating netrual wire cost of transmission can be reduced?

Transmission lines do not use a neutral conductor, so your question isn't actually relevant. Neutral wires are only necessary where imbalance may be large, and under some conditions current may be flowing in the neutral. Under these conditions a low impedance path (the neutral wire) is more desireable than a high impedance path (the ground). In many overhead transmission lines, a fourth or fifth wire are placed above the current carrying conductors; these are shield wires (not neutral wires) and are used to minimize outages on the line due to lightning (the lightning will strike these instead of the phase wires, these will flash over to the structures and the energy will be shorted to ground without the line having to be removed from service). When you're dealing with things that cost ~$100,000 - 2M/mile, it may be worth the added expense of a shield wire to keep it in service as much as possible.


What is a lossless transmission line?

A lossless transmission line is when no energy is lost during transmission of energy from a particular source to destination by a certain material, ie. copper wire. In other words, this material that transmits energy, absorbs none of the energy transmitted. No energy is lost to the material during transfer of energy. It is like saying it is an absolutely perfect conductor having no resistance.

What wire on a 3 line wooden pylon is live neutral and earth?

On a 3-line wooden pylon, typically the top wire is the live wire, the middle wire is the neutral wire, and the bottom wire is the earth wire. It is important to contact a professional electrician to properly identify and work with these wires to ensure safety.

How do you remove the quick connect on the transmission line?

there is a tool yo do it or you can use a very small screwdriver to pull the retaining wire out. be carefull not to bend it so much that it permanitly distorts. then the line just pulls out. all the wire does is hold the line in place there is a bulge in the line that it catches on then an o-ring that makes the seal. one last note if you have to replace the transmission fluid use atf+4 or you will destroy it.

What is difference between nutral and earth wire?

A neutral wire provides a return path for the hot lead while an earth or "ground" wire is provided as a safety function only that is not normally intended to carry current except for the purpose of operator protection.


White wire a black wire a red wire and a bare wire?

The white wire is typically neutral, the black wire is usually hot or live, the red wire may be a secondary live wire or used for a separate function, and the bare wire is typically the ground wire for safety purposes in an electrical circuit.


Why don't birds get electricuted while on a electric line?

To get electrocuted you need to complete an electrical circuit. That takes two wires or a wire and an "earth". A bird on a wire is not making a connection to a second wire or to the earth. Therefore no electricity flows and they are perfectly safe.


How do you tell which is the line wire and the load wire?

The line wire will be hot and carrying power when the breaker is on. The load wire will not be hot and will have no voltage on it until it is connected with the line wire.


How do you wire your 87 samurai backup lights bypassing the backup light transmission mounted switch?

You would have to literally run a wire from the battery through a fuse and then to a toggle switch and then on to the backup lights, this will only function when the switch is on and will have nothing to do with the transmission being in reverse. This is essentially the same as putting a toggle switch across the transmission mounted switch (assuming the transmission switch is not shorted).
