What Is Earthing ?

If you are studying electrical related then you must have heard about Earthing then if you do not know What is Earthing and Why it is important for us. And on which equipment, it is very important to do earthing. And what is the difference between earthing and neutral wire. We are going to give you all this information in this post.

While doing house Wiring, you have to take care of many things. While making the connection to the switch board, you have to keep in mind all the wires which have electricity and which are neutral or which have no electricity. Apart from this, we also connect another wire to the switch board which we call the earthing or grounding wire. But why is it important for us, not everyone knows. So that's why we are going to tell you in Electrical Earthing.

Definition of Earthing 

" Connection between the Metal part of any Metal machine or device to Earth Plate or Earth Electrode, This is called earthing or grounding. "

Earthing Symbol

For the earth plate or earth electrode we use a very thick wire. Use, whose resistance is very low. And there is also a reason for using low resistance wire for this. Which we are going to tell you further.

Why the earthing system is needed

The first reason for economizing any device is that we can avoid electric shock. Many times our equipment goes bad due to leakage current in the metal part of its equipment and which can cause us to touch it, then to avoid AC current, we make the earthing of the device so that whatever current With the help of that earthing, he goes straight into the earth. And we should not get electric shock.

1. Apart from this, some points of why we need earthing are given below.
2. Earthing protects our electrical equipment from leakage current and also protects us from electric shock.
3. It also protects the building from electricity falling during the rains.

Questions related to Electrical Earthing

Q. What is Earth ?

• Connecting any electric powered device to the earthing plate buried inside the earth by a wire is called Earth.

Q. What is Solidly Earthed ?

• Whenever an electrical device is connected directly to the Earth Electrode without a fuse circuit breaker and resistance it is called Solidly Earthed

Q. What is Earth Electrode ?

• When the plate of a conductor or conductor is pressed inside the earth for the earthing of an electrical device, it is called Earth Electrod. Earth Electrode can be of many types. It can be in the form of a plate. Can it be in the form of a metal water pipe with least resistance.

Q. What is Earthing Lead ?

• Earthing Lead is used to connect the Earth Electrode and equipment.

Q. What is Earth Continuity Conductor ?

• The conductor wire that connects all the electrical appliances of our house and the switch board and the eyelid is called the Earth Continuity Conductor.

Q. What is Earth Resistance ?

• Earth means the total resistance between the electrode and the electrical device that is measured in Oh (Ohms) is called Earth Resistance.

What are the types of Earthing ?

Earthing is done in many ways depending on where you were and where you want to work or for how much load, like in our house we don't need much dominating meaning but in a factory a big company In India, a larger meaning is required, but there is one or two places where earthing has to be taken. Below you have been told some types of earthing and one of these more ways is also explained how you can do earthing in your house.

1. Pipe Earthing

• For this earthing, at least 1.5 or 2 Inch thick iron pipe is used and its length is at least 8 to 9 feet. This earthing is very widely used method. In this method, the pipe is thickened 8 to 9 feet down in a damp place. It is covered with salt and coal around the pipe and it connects the earthing wire.

2. Rod Earthing

Rod Earthing

• Road earthing is also like pipe earthing, in which a copper road of 12 Mm is buried in the earth. The copper road is buried directly into the earth with the help of Pneumatic Hammer without digging a pit. And from this the earthing wire is connected.

3. Plate Earthing

• The plate earthing system consists of a copper plate sized 60cm X 60cm X 3.18mm (2ft X 2ft X 1/8 In). This copper plate is pressed 10 feet down into the earth. And this plate is placed in a humid place so that it can be interpreted better.

 Accessories for Earthing........

We need a lot of goods to do earthing but most of all we will need three things, whose names are given below.

1. Earth Continuity Conductor
2. Earthing lead
3. Earth Electrode

The resistance you use the Earth Continuity Conductor wire for earthing should not exceed 1Ω. Copper wire is always used for earthing. Whatever you had for earthing, it should be at least 6mm in size.

To connect the earthing wire to the earthing plate we use Earthing Lead, it should also be of copper as shown in the photo above. For greater security, you can use two earthing wire, for this you will have to install two earthing lead and earthing plate also. And meaning you have to make them Loop. You will lift it from the first earthing plate and take it to the device and put the second wire on the same device and drop it back down from the earthing plate so that your device will be more secure. You will use two earthing wire for larger equipment.

Earthing Electrode is always used of copper and iron, but copper is used for greater security. Earthing plate should be placed in a place where moisture can be done properly.

 How to make Earthing from Pipe at Home

Pipe Earthing

1. First of all, looking at the place of moisture, dig a pit there and the pit is 30 cm. × 30 cm The size should be 4.75 meters deep. You should use GI pipe. The length of this pipe is 2 meters and 38 mm. Must be a diameter. And will make 12 mm holes in the middle between this GI pipe. This pipe should be slanted from below.

2. After this, the GI pipe has to be reconnected with the pipe of Earth Electrode Reducing Socket. GI pipe we will use to keep moisture inside the ground. Now put both these pipes in the pit. Cover the funnel with water so that the soil does not get inside.

3. You have to make a hole inside this pipe and inside it you have to install 1 Net Bolt and washers with which we will connect our earthing wire. And connect the earthing wire to the pipe well with the help of this nut bolt and washer so that it does not become loose.

4. Then you have to put salt and coal inside the pit. You have to put at least 10-10 kg of salt and coal. And you do not have to put salt or coal together, first you have to add some salt, then some coal and then salt and again coal, by doing this, you have to make a layer by mixing the rest of the coal and salt.

5. After adding half the salt and coal, you have to pour light water over it so that the salt and coal freeze well.

6. And start adding salt and coal again, just as the layer was made on top of the first layer. And after adding all the salt and coal, spraying water again.

7. And then fill the soil in the pit. But whatever is the earthing wire, you take it out with the help of a separate thin plastic pipe. So that the effect of soil is not on our earthing wire.

8. Put a little bit out of the Earth Electrode pipe. Pour water in it and fill it completely and then fix it with cement concrete by putting bricks around it so that the lid can be put on it. And after filling this pipe with water, cover this pit.

9. Now the next day you can connect your earthing wire to it, it is ready to make the connection. To check this, you can use a bulb so that you can attach one wire to the phase wire and check the other wire by connecting it to the earthing.

 Precautions......!

1. Pipe should be fitted according to moisture in the pit.
2. The length and thickness of the pipe should be according to the law of electricity.
3. The bottom of the pipe should be slant.
4. And there should be some holes in the middle of the pipe so that when we pour water in the pipe, that water will keep moisture well all around.
5. The connection of any wire you connect to the pipe must be tightened.

 Plate Earthing......

1. Dig a pit more than 3 meters deep in the ground, whose width is 90 cm. × 90 cm Ho.
2. A copper plate for Earth Electrode whose size is 60 cm. × 60 cm × 3.18 mm or G.I. Plate size 60 cm × 60 cm × 35 mm Ho.
3.  Make holes in the middle of the plate.
4. Tighten the piece of wire, which is called Earthing Lead, with a plate with nut-volt.
5. Now place the plate vertically in the pit surface.
6.  15 cm around the plate Thickly fold salt and coal after each other until the plate is covered.
7. Earthing Lead 12–5 mm. Remove the diameter from inside the pipe.
8. A 19 mm Take the diameter pipe to the surface of the plate.
9. A funnel is 19 mm. Apply diameter on the upper surface of the pipe.
10. Close the pit with a cover-iron lid.
