> IMPORTANCE OF A SUITABLE EARTHING A well designed earthing system is basic for any electrical installation to avoid the danger associated with fault currents, as established in the main earthing standards: Spain: RBT2002 “Low Voltage Electrotechnical Regulation”. ITC-18 “Earthing systems”. Great Britain: BS 7430 “Code of practice for Earthing”. France: NF C 15-100 “Low Voltage Electrical Installations”. Germany: DIN VDE 0100 Part 540 “Earthing arrangements, protective conductors, equipotential bonding conductors” USA: UL 467 “Grounding and bonding equipment”. A LOW VOLTAGE EARTH...

133 > APLIROD® DYNAMIC ELECTRODE A lack of free ions in the surrounding ground is detrimental to the correct performance of the earthing. Earthing systems using dynamic electrodes are based on the contribution of ions to the ground. The system mainly consists of a copper electrode (APLIROD®) filled with a mixture of ionic compounds. The moisture condenser absorbs environmental moisture and dissipates it in the soil surrounding the electrode, adding free ions and gradually lowering the resistivity of the soil. The effectiveness of this earth electrode is improved by placing a ground...

134 > GRAPHITE ELECTRODE The fact that graphite exhibits high electrical and thermal conductivity and is unassailable and inert to chemical agents (apart from oxygen at a high temperature), makes it a very suitable element for building an earth electrode. The materials used as filling (graphite powder and thin claylike powder) ensure contact between the electrode and the ground thanks to its capacity to penetrate even cracks in rocks. 1.5 x 1.5 x 2 meter hole Machinery needed: > Backhoe INSTALLATION The reference AT-070H consists of a rigid graphite core surrounded by a layer of graphite...

APLICACIONES TECNOLOGICAS > EARTH ELECTRODES, GROUND ENHANCING PRODUCTS AND EARTH PITS INSTALLATION The electrodes should be placed at a depth of at least 50 cm. It is preferable to use several conductors conveniently spread out rather than one very long conductor. In the case of an earthing system made up of various interconnected electrodes, it is recommended that: > The buried earth rods must be placed in a triangle or line and spaced out at a distance of at least that of their buried depth. > The buried earth rods are connected by an identical or compatible conductor to the one used for...

136 > SOLID COPPER EARTH RODS Solid copper rods enable long-lasting earthing in ground with high corrosion levels. Threaded electrodes with the correct accessories enable the length to be increased, thus achieving a better earth resistance. Stainless steel earth rods enable long-lasting earthing in ground with high corrosion levels. Threaded electrodes with the correct accessories enable the length to be increased, thus achieving a better earth resistance.

141 > EARTH PLATES The use of earth plates as electrodes significantly reduces the resistance of earthing in stony grounds, as it increases the area of contact between the electrode and the ground. The references AT-116H and AT-122H comply with the minimum dimensions recommended in the Technical Guide for implementing no. 18 of the Spanish Low Voltage Electrotechnical Regulations of 2002. Mesh earthing systems are a more cost-effective option than earth plates and still work well in stony ground, reducing the step or contact voltages that may occur. AT-070J is recommended to avoid step...

APLICACIONES TECNOLOGICAS > EARTH ELECTRODES, GROUND ENHANCING PRODUCTS AND EARTH PITS Strips to protect buried connections from corrosion. 144 > EARTH PITS Aplicaciones Tecnologicas earth pits cover all industrial and commercial applications as they are available in 3 materials: polypropylene, concrete and cast iron. AT-010H can withstand 5,000 kg loads. The main advantage of this earth pit is: > Designed to facilitate handling and storage. > Good resistance to chemical substances. > Resistant to UV rays. > Attached using two individual screws

CONDUCTIVER PLUS is a ground enhancing gel with low solubility which is, nonetheless, very hygroscopic. It is made of an electrolyte base, which contributes to the conductivity of the mixture. The conductivity of the ground is almost exclusively of an electrolytic nature due to the salts dispersed in the water which impregnate it and concentrate on the surface due to adhesion of the sand grains and clay in the ground. It is therefore possible to increase the conductivity of the ground, improving its absorption power, water retention and increasing its concentration of soluble salts. It...

APLICACIONES TECNOLOGICAS > EARTH ELECTRODES, GROUND ENHANCING PRODUCTS AND EARTH PITS In high resistivity soils it is necessary to use a specific material to obtain a suitable grounding resistance. APLICEM ground enhancing cement improves grounding effectiveness around any type of earthing rod. This product is very useful in industries that require a low grounding resistance such as computer installations, radio frequency facilities and substations etc. APLICEM increases the conductive surface of the earth electrode, reducing the earthing resistance of the loose electrode. Additionally,...
