Keep Safety Standards in Mind While Selecting Pipe Earthing

The Earth is the connection between all the neutral points in the system’s supply to produce an immediate electric power discharge without risk during a failure. Earth provides the flowing failure current with an alternate path and ensures that not all exposed leading materials achieve their corresponding maximum potential. A suitable method of earthing always has a low impedance to ensure adequate current can flow through the security device during failure current and can be removed from the supply. A good earthing system protects staff from electrical risks and protects electrical equipment from current leaks. Properly designed earthing also prevents interference with the system’s communication wires.

  • Plate Earthing- A platform consisting of galvanized copper or iron is vertically sunk in this type of earth at a depth not less than 3m from the ground level. All the conductors are connected to the ground.
  • Pipe Earthing- A vertical galvanized pipe in this form of earth connects all electrical conductors with the soil, in which the depth of the pipe depends on soil conditions. Pipe earthing, compared to other earthing technologies, is an economic sort of earthwork.
  • Rod Earthing- This method contains a vertical burial at a depth of not less than 2.5m of a 16 mm diameter copper rod and galvanized steel or 25 mm hollow part. This is like a built-in electrode that reduces the resistance of the Earth to the required value. The rod earthing procedure is comparable to the rod earthing process.

Various factors, like human and equipment safety standards, must be addressed when selecting the Pipe Type Earthing that is being used. The ability to maintain supply at various voltage levels while avoiding threats and hazards.

In comparison to alternative earthing systems suitable for the same earth and moisture conditions, pipe earthing is the most prevalent and best system. This approach involves placing a galvanized steel and perforated pipe of appropriate length and diameter upright in continually damp soil. The pipe’s size is determined by the amount of current to be transported and the kind of soil. For standard soil, a pipe with a diameter of 40 mm and a length of 2.5 meters is used, while for dry and rocky soil, a pipe with a diameter of 40 mm, and a length of greater than 2.5 meters is used. The depth to which the pipe must be buried is determined by the ground’s moisture content.

People may have heard about voltage fluctuations and how they might affect structures. Kids would have learned about the effects of lightning on structures. Shield wire earthing is utilized for the same purpose, to safeguard buildings from such attacks and overall collapse. However, if they are unfamiliar with it, they may be interested in learning more.

Bird guards are barriers that assist in preventing birds from perching on transmission structures. These are simple structures that consist of a square ground with stiff prongs constructed of non-conductive, weather-proof, and long-lasting materials. They are mostly determined by the needs of the power company as well as the size of the lines that must be maintained.

What are the advantages of using bird guards?

For a variety of reasons, it is in the best interests of power suppliers to place bird guards on new and existing transmission structures:

  • To avoid faults and flashovers that would cause power outages in the communities served.
  • To reduce the cost of maintenance and the expense of repairing structures and lines following a flashover.
  • To keep birds from building nests on transmission towers.
  • To aid in the prevention of bird deaths due to electricity and fire.
  • To have a favourable impact on the conservation of a wide range of bird species, particularly larger birds of prey.

Birds can cause numerous types of damage to transmission lines and structures. This may have an impact on more than just them and their chicks. However, due to the threat of fire, it could be dangerous for others as well as surrounding homes. This is why shield wire earthing is important since it aids in the creation of bird guards. To avoid power outages and possible defects caused by birds excreting on power lines as well as nesting on them.
