Leading The Nation Towards Electrical Safety Best practice for shielding and linking to the reference earth Earthing system is a much beaten up subject that should be handled with caution. To create a solid and stable earthing installation it must be complying to all relevant codes and standards. A ground connection is a base to every electrical installation. Primary intention of the concept is to protect people and secondly, it aims at safeguarding structure and the equipment from damage and fire. There is hardly any equipment that does not need protection. Equipment/ circuitry devoid of earth connection will lead to unintentional contact of high energy lines with people or any such conducting elements via which this fault current will get discharged to the ground.
Leading The Nation Towards Electrical Safety Going back to the time when good electrical earth connection was not so common, was when the connections/ wiring was less complex and so did the internal circuitry o the appliances. While now we have highly complex and expensive appliances that needs to be plugged to the ground. Agreeing on the ground link is not enough, the way you link is another important topic to be thought of. You have conventional techniques such as using GI or Copper plate or pipes along with salt and charcoal mix. Opting conventional earthing set up is like opting for a temporary and unreliable protection scheme as this technique simply does not last long and they also require frequent maintenance and renewal of the system. The worse case scenario would be that the installed protection will get corroded easily with the conductor.
Leading The Nation Towards Electrical Safety There are millions of studies and research that can suggest you a better protection system. Maintenance free earthing is an advance methodology where we use copper bonded steel rods as conductors driven deep under the earth. Copper bonded steel rods is a blend of pure 250 microns copper coated on high tensile low carbon steel core. Proper earthing technique aids in superior conductivity and durability. It ensures a low resistant path for the fault current and stabilizes the voltage to a threshold value during its normal operation. 250 microns copper coating of pure electrolytic form of copper on steel offers superior conductivity. Copper is molecularly bonded to steel that resist corrosion and stays under the earth for a really longer period of time. Earth enhancement compound used in conjunction is another aspect to improve the conductivity of the system. Earth enhancement compound increases the conductivity of the soil surrounding the earth electrode.
