The earthing system design is utilized in each of the electrical installations made in the buildings. This concept is also referred to as a grounding system which is based upon circuit connecting parts in the electrical system that is connected to the ground. It will help in regulating the conductors with the respect to conducting surface of the earth which is the main reason the term earthing is associated with this concept.
Earthing is considered to be a very modern component of the electrical type of systems due to the reasons which have been mentioned as follows:
-It will help in keeping the people safe and secure by preventing them from electrical shocks
-It will help in preventing the damage to the electrical appliances by preventing the excessive amount of current from running throughout the circuit
-It will help in preventing the risk associated with fire which can be there because of the leakage of current.
Following are some of the advantages provided by the concept of earthing:
-The electrical type of system is very well related to the whole potential of the general mass of the earth and cannot reach a different kind of potential. The potential of the mother earth is considered to be 0 V and it is also known as the neutral electrical supply. So, this is the main benefit of the system of lightning connection and earthing system because it will help in maintaining the balance throughout the whole thing.
-Another great advantage associated with the concept of earthing is that it is based upon metals which can be utilized in the electrical installations and there will be no need to worry about the concept of conductivity. Metal is considered to be a great conductor of electricity so proper earthing will help to ensure that metal parts are not used in the current transfer of the whole thing into the systems. Nothing will be done through different parts which have been there for the faulty current and will enable its immediate stoppage as well as detection.
-In all the cases of a high surge in the voltage, the high-voltage will pass through the electrical circuit and these kinds of overloads will lead to a lot of damage the devices and will cause great amount of danger to the human life. But the installation of electrical earthing systems will help to make sure that current is always routed through a different path and never affects the electrical systems adversely.
-The whole electrical circuit must be connected and proper attention has to be paid to it because it will help in preventing various reactions as it will not provide any of the response to the transformer.
Some of the most common types of earning undertaken into several organizations have been explained as follows:
-The plate type of earthing: This type of earthing is based upon copper and galvanized iron which has to be buried very well and vertically into the earth by digging earth. The pit has to be dug for approximately more than 9 feet into the ground and these kinds of rods are filled with charcoal as well as salt into alternate layers to ensure the overall system is very well implemented.
– The pipe type of earthing: In this type of earthing, a good quality pipe made of galvanized steel has to be placed into the soil rather than the plates. After this, the whole pipe is dealt with several kinds of roles so that earthing wires can be connected. The length, as well as the pipe diameter, will depend upon the soil types along with the types of electrical installation undertaken by the organization. The earth pits which are made are also filled with the alternate layers of both salt as well as charcoal so that reactivity is reduced. This type of earthing is considered to be the most commonly implemented type of earthing by the organizations.
-The rod earthing: It is considered to be highly similar to the pipe type of earthing and requires proper burying of the rod which is made of galvanized iron or copper. The electrodes are also embedded into the soil which helps in decreasing the whole resistance of the earth as and when required throughout the process.
-The wire type of earthing: This kind of earthing will help to make sure that the whole system is very well implemented and for this purpose horizontal type of trenches are dug into the earth. Strip type of electrodes is buried deep inside the trenches and several kinds of electrodes are also made of galvanized iron or copper. In some of the cases, the organizations also go with the usage of round conductors into the ground.
-The water man method: The water man method uses the galvanized GI pipes along with water man pipes. After these kinds of pipes are buried into the earth, clamps are also used to ensure the reduced resistance of the electrical connections.
No matter with which of the method any of the organizations go, the basic thing to be ensured is that it is very much important to decide about the sizes of the devices, the depth of burying it. You also need to ensure its proper connection to the electrical type of installations and everything is done with proper care after calculating the in-depth calculations so that whole order can become very much effective. Several factors help in influencing the whole installation of the guarding systems. These kinds of factors have to be properly considered so that accurate calculations are made. The type of soil is very much important to ensure proper implementation of the earthing systems. The distance of earth, moisture level, salts present in the soil will also help in determining the method. The soil and its composition is another factor that helps to influence the whole decision depending upon the soil type.
Hence, the best earthing system is based upon the above-mentioned factors so that accuracy in the calculation is there and overall goals are very well achieved. So, employ that earthing system which matches with the factors mentioned above. Because earthing is the only way by which you can safeguard yourselves from electric current.
