What are the 2 major types of earthing ?

Earthing, also known as grounding, is a critical aspect of electrical systems. It is essential to provide a safe path for electricity to flow into the ground in case of a fault. The two major types of earthing are electrode earthing and plate earthing. In this article, we will explore these two types and understand their differences.

Electrode Earthing

Electrode earthing is the most common type of earthing. It involves connecting a metal electrode to a conductive material, such as a copper wire, and then connecting the electrode to the ground. This type of earthing is also known as a "solid earthing" or "through-the-solid earthing." In this type of earthing, the risk of electrical shock is high, as the user is directly connected to the ground.

Plate Earthing

Plate earthing is the other major type of earthing. It involves connecting a metal plate or shield to a conductive material, such as a copper pipe, and then connecting the plate to the ground. This type of earthing is also known as a "through-the-pipe earthing" or "solid-through-the-pipe earthing." In this type of earthing, the risk of electrical shock is low, as the user is not directly connected to the ground.

Understanding the Differences

While both electrode earthing and plate earthing are effective at providing a safe path for electricity to flow into the ground, there are some key differences between them. The most obvious difference is the risk of electrical shock. In electrode earthing, the user is directly connected to the ground, which increases the risk of electrical shock. In plate earthing, the user is not directly connected to the ground, which reduces the risk of electrical shock.

Other differences between the two types of earthing include the ease of use and the cost. electrode earthing is typically more difficult to use and more expensive than plate earthing. However, plate earthing is easier to use and less expensive than electrode earthing.

Conclusion

In conclusion, there are two major types of earthing - electrode earthing and plate earthing. While both types of earthing provide a safe path for electricity to flow into the ground, it is essential to understand the differences between them and choose the type that best suits your needs.
