Have you ever felt a slight shock when touching some appliances while they are on and functioning? These shocks can occasionally pose serious risks and be dangerous. It is generally advisable to have the building properly earthed to prevent accidents.There are also various types of earthing, which you’ll learn about in this article. The devices are shielded from electrical damage by the earth, which is straightforward for current leakage. In addition to balancing the load when the electrical system overloads grounding is a safety procedure that safeguards the entire power system from malfunctioning.

Types of Earthing

Now you have got to know what is meant by Earthing, but let’s see what are the types of earthing.

1. Pipe Earthing

In India, pipe earthing is a popular method of connecting to the electrical conductors of the earth by use of a steel pipe. The amount of soil moisture and the strength of the current effect the iron pipe's size. The depth at which the steel pipe is to be installed depends on the moisture content of the soil.


2. Plate Earthing

An earthing plate consisting of copper or G.I. is buried into the ground during plate earthing at a depth greater than 3 meters below ground level. A different layer of coke and salts surrounds this earthing plate.
Additionally, earthing can make lightning protection systems better. Static charges and stray current mishaps can be avoided by plate earthing. In order to meet the earthing safety criteria for the electrical substation, it protects systems like central communication, electronic, and AC power systems.



3. Mat Earthing

It joins vertical and horizontal electrodes; the horizontal electrode discharges current produced by a large fault into the earth, while the vertical electrode represses it. To improve safety against touch and step potential, an Earth Mat is a mesh made of bare metallic conductors that are buried in shallow soil. Earth mats are a component of the grounding system used in industrial regions, substations, and other locations with significant power handling.



4. Stripe Earthing

Strip earthing creates a channel that makes it simple for current to pass from broken electrical devices to the ground. The strips are further protected from the soil's corrosive properties by a layer of high-quality insulating material. Therefore, utilizing the strip earthing approach, all electrical appliances should be grounded for safety reasons.
The earth stripping procedure is used to ground current primarily using copper strips. Copper earthing strips last longer and provide superior voltage transient protection because they are so resistant to corrosion.



5. Marconite Earthing

The safest earthing method, known as marconite earthing, uses low-resistant copper earth electrodes that are especially created to provide solar power plants with an earthing system of the highest caliber. It is a dark grey substance that is combined with cement and water to create an earthing system that is secure and safe.
