if you study or do electrical work. So you must have heard these two words earthing and grounding, and then you must have thought about what earthing and grounding is, and what is the difference between earthing and grounding.

So today we will first tell you what is Earthing Grounding. After this, we will explain the difference between these two. First of all, you have to remember that both earthing and grounding are done in one way. Meaning, inside both of them, a wire is lifted deep into the ground and a wire is removed from it. But now where we are connecting this wire removed from the ground, it makes a difference whether it will be called earthing or grounding.

Difference between earthing and grounding

Inside the earthing, first of all we take a wire deep inside the ground and take out a wire from there. Now we connect this wire to the body of our electrical appliance. This earthing wire is attached on a device made of body metal. Because current on a body made of metal flows easily. Need of earthing- After earthing, if for any reason the supply wire gets crowded to the body of the equipment. So at that time the current will start going underground with the help of our earth wire. Meanwhile, even if someone comes and touches the body of the device, it does not feel current.

How Many Types of Earthing In India ?

Electrical grounding, also known as earthing, is done in several ways like housing, wiring, electrical device, and more. The different types of electrical earthing systems in India are:

1: Pipe Earthing
Pipe earthing is a common form of earthing in India that uses a steel pipe to connect with the earth’s electrical conductors. The size of the iron pipe depends on the soil moisture and the magnitude of the current. The soil’s moisture will decide the depth for the placement of the steel pipe.

2: Plate Earthing
Plate earthing is where a copper plate is distanced at 3 meters from the earth and vertically placed in the ground pit.

3: Mat Earthing
Mat earthing connects vertical and horizontal electrodes – a horizontal electrode represses the current generated due to a massive fault while the vertical electrode dissipates the current into the earth.

What is earthing or grounding ?

Inside the grounding also, like earthing, a wire is first pulled out into the ground. But during grounding, we do not connect this wire to the body of the equipment. During grounding, we connect the earth wire to the neutral of the live supply. Grounding is used to better find the way to the current.

Earthing and Grounding Difference ?

Earthing – Earthing is used for our safety when we have an electrical fault.

● Earthing is used for our safety in case of electrical fault.

Grounding- Grounding is used for the safety of electrical equipment when we have an electrical fault.

● Grounding is used for the safety of electrical equipment when an electrical fault occurs.

Difference between earthing and grounding ?

  • In earthing we connect the body and ground of the equipment. But during grounding, we connect the neutral of the electrical circuit to the ground.

  •  Mostly black wire is used for grounding. And green wire is used for earthing,

  • Earthing is used to avoid electrical shock. But the main use of grounding is to protect the three phase electrical system from being unbalance.

  • Inside the grounding, the live part in which current is flowing is added to the ground. But at the time of earthing the dead part is attached to the ground. That means the part which is not in contact with the current in normal condition.

Example: We ground the neutral mean (star connection) of transformer and generator. This is called grounding.

Whereas when we transformer or any device which is made of body metal. We connect it to the ground for protection from our electrical shock, it is called earthing.

How does a grounding mat work?

Debra Rose Wilson: A grounding mat is meant to replace the direct contact with the earth that we would get if we walked barefoot. In current Western culture, we seldom walk barefoot outside.

The earth’s surface has a negative electric charge, and when it comes in contact with human tissue, there is an equalization. The body can take on extra electrons and build up a static electric charge. This is called the Earthing hypothesis.

A grounding mat mimics the electric current of the earth and allows a person to bring the experience into a home or office. Most of the biochemical reactions in the body involve electron transfer.

That said, this isn’t for everyone. There is the potential danger of drawing current from other sources, so be aware of unground electrical sources near you. This could cause a potentially dangerous electrical shock.

Debra Sullivan: Grounding or earthing mats create an electrical connection between your body and the earth. The idea is to replicate the physical connectivity one would make by walking barefoot on the ground. This connection allows electrons to flow from the earth and into your body to create a neutral electrical charge.

Since humans spend the majority of time either indoors or wearing rubber-soled shoes outdoors, we barely spend time having physical contact with the earth. These mats allow for this connection when indoors and re-creates that equilibrium of electron charge.

Grounding mats are meant to bring a connection to earth indoors. The mats usually connect via a wire to the ground port of an electrical outlet. The mats may be placed on the floor, on a desk, or on a bed so the user can put their bare feet, hands, or body on the mat and conduct the earth’s energy.
