  • Best type of earthing

    Earthing is an essential aspect of electrical systems, as it protects people and equipment from the dangers of electrical faults. Electrical faults can occur due to various reasons, such as lightning strikes, equipment failure, and insulation breakdown. In such situations, earthing provides a low impedance path to ground, which prevents electrical currents from flowing through people and equipment. There are several types of earthing systems, and in this article, we will discuss chemical earthing, which is considered the best type of earthing. We will also discuss the components of chemical earthing, such as copper bonded rods, earth enhancement compounds, and FRP earth pit covers, which make it superior to conventional earthing.

    Conventional Earthing

    Conventional earthing involves burying a metal conductor, such as a copper rod or a galvanized iron pipe, in the ground. The conductor is connected to the electrical system, and its other end is buried deep in the ground. The depth of the conductor depends on several factors, such as the type of soil, the moisture content, and the electrical load. The objective of conventional earthing is to provide a low impedance path to ground, which limits the voltage rise in the event of an electrical fault.

    Conventional earthing has several limitations, which make it less effective compared to chemical earthing. Some of these limitations include:

    Corrosion – Metal conductors used in conventional earthing are prone to corrosion, which reduces their effectiveness over time. Corrosion can also lead to an increase in the resistance of the conductor, which results in higher voltage drops.

    Soil Conditions – The effectiveness of conventional earthing depends on soil conditions, such as moisture content and soil resistivity. In dry soils, the resistance of the conductor may increase, reducing its effectiveness.

    Maintenance – Conventional earthing requires regular maintenance, such as cleaning and inspection, to ensure its effectiveness. Neglecting maintenance can lead to corrosion and increased resistance.

    Chemical Earthing

    Earthing Materials

    Chemical earthing, also known as maintenance-free earthing, is a modern type of earthing that overcomes the limitations of conventional earthing. Chemical earthing involves burying a copper bonded rod in the ground, which is filled with a conductive compound known as earth enhancement compound (EEC). The EEC is a mixture of conductive salts and minerals that provide a low impedance path to ground, even in dry soils. The EEC is also resistant to corrosion, which ensures the longevity of the earthing system.

    Components of Chemical Earthing

    Copper Bonded Rods

    Copper bonded rods are the main component of chemical earthing. These rods are made by bonding a layer of copper to a steel core using a high-pressure process. The copper layer provides excellent conductivity, while the steel core provides strength and durability. Copper bonded rods are available in different lengths and diameters, depending on the electrical load and soil conditions.

    Earth Enhancement Compound (EEC)

    The earth enhancement compound is a mixture of conductive salts and minerals that are used to fill the borehole around the copper bonded rod. The EEC is designed to improve the conductivity of the soil, even in dry conditions. The EEC is also resistant to corrosion, which ensures the longevity of the earthing system. The EEC is available in different grades, depending on the soil conditions and electrical load.

    FRP Earth Pit Cover

    FRP earth pit covers are used to cover the borehole and the EEC to protect them from environmental factors, such as rain, dust, and animals. FRP (Fiber Reinforced Plastic) is a lightweight and durable material that is resistant to corrosion and UV radiation. FRP earth pit covers are available in different sizes and shapes, depending on the size of the borehole and the electrical load.

    Advantages of Chemical Earthing

    Chemical earthing has several advantages over conventional earthing, some of which include:

    Resistance to Corrosion

    Copper bonded rods used in chemical earthing are resistant to corrosion, which ensures the longevity of the earthing system. The EEC is also resistant to corrosion, which further improves the effectiveness of the earthing system.

    Maintenance-Free

    Chemical earthing is a maintenance-free system, which reduces the maintenance costs and ensures the reliability of the earthing system.

    Easy Installation

    Chemical earthing is easy to install and requires minimal excavation. The installation process involves drilling a borehole, inserting the copper bonded rod, and filling the borehole with the earth enhancement compound. The FRP earth pit cover is then installed to protect the borehole and the EEC.

    Applications of Chemical Earthing

    Chemical earthing is used in a wide range of applications, some of which include:

    Telecommunications – Chemical earthing is used in telecommunications systems to protect the equipment from lightning strikes and electrical faults. The low impedance path to ground provided by chemical earthing ensures the safety of the equipment and the personnel.

  • Earthing materials in Patna, Bihar

    Earthing refers to the process of connecting the electrical system of a building to the ground to protect it from surges and lightning strikes. The process is essential for the safe operation of electrical systems, as it provides a low resistance path for electricity to flow to the earth in case of any faults.

    Patna, the capital of Bihar, is a rapidly developing city that has witnessed a significant increase in the number of buildings and infrastructure projects over the last decade. These developments require proper earthing systems to ensure the safety of the buildings and the people inside them.

    There are two types of earthing systems: conventional earthing and chemical earthing. In this article, we will discuss both types of earthing systems and the earthing materials used in Patna, Bihar.

    Conventional Earthing System

    Conventional earthing systems have been in use for many years and involve the use of earthing pipes, earthing rods, charcoal, salt, and other materials. These materials are easily available and cost-effective, making them a popular choice for conventional earthing systems.

    Earthing Pipe

    Earthing pipes are a type of metal pipe that is installed vertically in the ground. The pipe is made of copper or GI (Galvanized Iron) and is buried in a pit that is filled with a mixture of charcoal and salt. The earthing pipe is connected to the electrical system of the building, and the earth wire is attached to the pipe.

    The earthing pipe is an effective way to provide a low resistance path for electrical currents to flow to the ground. The salt and charcoal mixture in the pit helps to maintain the moisture level in the soil, which is essential for effective earthing.

    Earthing Rod

    Earthing rods are another type of earthing material that is commonly used in conventional earthing systems. The rod is made of copper or GI and is installed vertically in the ground. The earthing rod is connected to the electrical system of the building, and the earth wire is attached to the rod.

    The earthing rod is effective in providing a low resistance path for electrical currents to flow to the ground. However, the rod requires a large amount of space in the ground, and the installation process can be challenging.

    Charcoal and Salt

    Charcoal and salt are commonly used in conventional earthing systems to maintain the moisture level in the soil around the earthing material. The moisture helps to provide a low resistance path for electrical currents to flow to the ground.

    The charcoal and salt mixture is filled in the earthing pit around the earthing pipe or rod. The mixture needs to be replenished regularly to maintain the moisture level in the soil.

    Chemical Earthing System

    Earthing Materials

    Chemical earthing systems are a relatively new technology that has gained popularity in recent years. The system involves the use of chemical compounds that are specially designed to enhance the conductivity of the soil around the earthing material. This results in a lower resistance path for electrical currents to flow to the ground.

    Copper Bonded Rod

    Copper bonded rods are one of the most commonly used earthing materials in chemical earthing systems. The rod is made of steel and is coated with a layer of copper that is bonded to the steel. The rod is installed vertically in the ground and connected to the electrical system of the building.

    The copper bonded rod provides an excellent low resistance path for electrical currents to flow to the ground. The copper coating helps to enhance the conductivity of the soil around the rod, resulting in a more efficient earthing system.

    Earth Enhancement Compound

    Earth enhancement compound is a chemical compound that is specially designed to enhance the conductivity of the soil around the earthing material. The compound is made of a mixture of natural materials and is added to the earthing pit around the earthing material.

    The compound helps to reduce the resistance of the soil and provides a efficient low resistance path for electrical currents to flow to the ground. It also helps to maintain the moisture level in the soil, reducing the need for regular replenishment of the earthing pit.

    FRP Earth Pit Cover

    FRP (Fiber Reinforced Plastic) earth pit covers are used to cover the earthing pit in chemical earthing systems. The covers are made of a durable and corrosion-resistant material that can withstand harsh weather conditions and provide protection to the earthing pit.

    The FRP earth pit covers are also designed to provide easy access to the earthing pit for maintenance and inspection purposes. They are available in various sizes and shapes to fit different types of earthing pits.

    Advantages and Disadvantages of Conventional and Chemical Earthing Systems

    Both conventional and chemical earthing systems have their advantages and disadvantages. Conventional earthing systems are cost-effective and easy to install, but they require regular maintenance to ensure their effectiveness. Chemical earthing systems, on the other hand, are more efficient and require less maintenance, but they can be more expensive than conventional systems.

    Conventional earthing systems are more prone to corrosion and can deteriorate over time, resulting in a higher resistance path for electrical currents to flow to the ground. Chemical earthing systems, on the other hand, are designed to last for many years and provide a consistent low resistance path for electrical currents.

    Earthing systems are an essential aspect of building safety and should be installed and maintained properly. Patna, Bihar, has seen significant development over the last decade, resulting in the need for proper earthing systems in buildings and infrastructure projects.

    Conventional earthing systems, such as earthing pipes, earthing rods, charcoal, and salt, are still widely used in Patna. However, chemical earthing systems, such as copper bonded rods, earth enhancement compounds, and FRP earth pit covers, are gaining popularity due to their efficiency and durability.

    Both conventional and chemical earthing systems have their advantages and disadvantages, and the choice of earthing system should depend on the specific requirements and budget of the project.
