Lightning is more of electricity that strikes in cloudy weather and changing weather. Every second he tries to hit the ground a hundred times. If it hits a structure in a building, it could cause electrical shocks and cause machinery and equipment to malfunction. Cable phones, wires, TV cables, electrical appliances, computers, metal doors, etc. that comes from electricity can cause damage. If the light comes into contact with a higher voltage line, the danger of high voltage may be transmitted to the electricity distribution system. In principle, every electrical installation must have a good and reliable earthing system. Good earthing systems are essential for
-Safety of human and animal life.
-Limited damage to electrical equipment in the event of a faulty flash.
-Timely operation of protective equipment.
The resistance of the ground electrode depends only on the resistivity of the ground and the type of electrodes used. Typically, a cast-iron GI plate/pipe is used as the electrode for grounding. The hole is dug and the electrode is placed in the middle and filled with soil mixed with salt and charcoal. The conductivity current of conventional electrodes is electrolytic. Therefore, regular watering and recharging of the earth salt pit are very important to keep the soil resistance low.
Regular maintenance of ground electrodes has become a challenging design for the following reasons.
A typical installation requires 4 types of grounding (safety, system, electronic and lightning)
In many commercial projects in cities, the land is only possible in basements.
In projects where open space is used for the soil, landscaping is carried out, where the electrodes are completely closed / hidden in the ground. Even where the electrodes are accessible, willingness to maintain is either lacking or not happening.
Moisture plays an important role in electrode resistance. India is a tropical country with almost 9 months of summer, so it is difficult to provide irrigation according to the recommendations of Indian standards.
Even with an increase in moisture content to 5% in summer, the pit in the ground requires 4,000 liters of water, which is impossible with extreme shortages. After all, due to these practical limitations, electrode irrigation and salt charging are not always performed and the supplied salt also dissolves over time due to precipitation (in many places within 2-3 years). This increases durability and makes the soil inefficient. In short, the limitations of the conventional terrestrial system are:
No standardization – Neither on the electrode nor on the backfill
In most cases, a commercial GI cast iron plate/pipe is used as the electrode
The backfill (SALT) will react with the electrode and cause corrosion
The salt dissolves in water and the conductivity decreases over time, increasing resistance.
Not suitable for areas with high groundwater levels, running water and the like.
Nowadays, residual current always flows through the electrodes through harmonics, load imbalances, etc., which contributes to corrosion.
Therefore, the use of maintenance-free earthing solutions is recommended. Maintenance-free grounding is possible by treating the soil around the critical area of the electrode.
The GI earthing electrode protects individuals from current shock caused by lightning by securely conducting fault current to the ground. Galvanized Iron (GI) earthing electrodes are made by placing a zinc layer over iron using a technique known as galvanization. The supplied electrode is frequently used to safeguard people from electrocution in telecommunication towers, microwave antennas, residential regions, and industrial locations. Our products are used in transmission and distribution systems, substations, and power plants. Chemical earthing electrodes are the finest alternative for nearly all types of earthing from a technical standpoint. Some of the more common names on the market include GI Earthing Rod, GI Earthing Electrode, GI Chemical Earthing Rod, and GI Pipe Earthing Electrode. The GI Earthing Electrode is a component of the chemical earthing system, and it is simple to install.
There are lots of chemical earthing manufacturers in the market but one of the best and trustworthy brands is Renown Earth which is a manufacturing company with a wide range of products.
