Earthing is the least visible but most decisive component of an electrical installation.<\/strong> The dispersion of the lightning current into the ground, the safe discharge of fault currents and the protection of human life all depend on this system. However carefully the air terminal is chosen, if the earthing is weak the system will not deliver the protection expected of it.<\/p>

The correctness and the selection of the equipment used matter as much as the earthing design and its calculations. At Y\u0131lkomer we hold in stock every product needed to earth a facility; alongside this we provide survey, calculation, design and installation support from a single source.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tThe same electrode gives a completely different result in sandy soil than in clay soil. The first step in a correct design is to measure the soil resistivity on site. Without this measurement, the number and depth of the electrodes chosen is no more than guesswork; in high-resistivity soils it often falls short.\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tRod electrode, angle-bar electrode, strip conductor or ring earth electrode \u2014 which of these is used is determined by the soil structure, the condition of the existing building and the target resistance. On the material side, hot-dip galvanised steel, copper-bonded steel and solid copper offer different balances of service life and cost.\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tThe weakest point of an earthing network is almost always the connections. Mechanical clamps loosen over time and are open to corrosion; exothermic (thermite) welded connections, by contrast, become one with the conductor, provide the same current-carrying capacity and stay sealed against corrosion underground. At points where dissimilar metals meet, the risk of galvanic corrosion must also be taken into account.\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tOnce the earthing is buried it disappears from view; for this reason inspection pits and test points must be built into the design from the outset.
