How to Calculate size of Earting Conductor and Earthing Electrodes? // Earthing Calculation.
There are mainly 4 types of Earthing Systems in India, Plate Earthing, Pipe Earthing, Mat Earthing, and Rod Earthing.
Pipe earthing is one of the popular earthing systems in India that suits every soil type. Earthing in large-scale residential, as well as commercial areas, prevents mishappenings on account of electrical shock. It protects your building and the electric boxes that are home to different types of electrical wires or cables.
Pipe earthing is joining a steel pipe with the earth’s electrical conductors. An Iron and steel pipe can transfer fault currents in electrical systems efficiently.
Earthing involves discharging electricity to the earth via low resistance electrical cables to prevent voltage surges resulting from an improper earthing system. Short circuits are a result of loose insulation and may occur anytime. However, a grounding wire may prevent these damages that can also be easily removed by technicians later.
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.
4: Marconite Earthing
Marconite earthing is the safest earthing technology that uses low-resistant copper earth electrodes that are specially manufactured to deliver a premium quality earthing system for solar power plants. It is a dark grey material that is mixed with cement and water to produce safe and secure earthing system.
