How are rays formed?<\/strong><\/p>\n

Usually the positive charges are located at the top of the cloud and the negative ones at the bottom.<\/p>\n

Statistical studies carried out around the world show that 95% of the clouds have a negative charge in their lower part. TERRAGAUSS Electromagnetic Lightning Rod System Formation of lightning and the importance of having a lightning rod in a facility.<\/p>\n

When there is an excess of charges, they look for a discharge path to ground, generating lightning.<\/p>\n

Usually the clouds send negatively charged descending guides and the earth sends positively charged ascending guides. When these guides touch, the dielectric rigidity of the air is broken and lightning is formed, which is accompanied by high temperatures, voltages and currents.<\/p>\n

\"\"<\/p>\n

The precipitated electric discharge of lightning is accompanied by the emission of light (the lightning caused by the passage of electric current, which ionizes the
air molecules, and by the sound of thunder, developed by the shock wave.<\/p>\n

How does lightning cause injury?<\/strong><\/p>\n

\u2022 Direct electric shock:<\/p>\n

Victims can receive a direct electric shock, a large amount of energy passes through the body in a very short time Its impact is so brutal that the electric shock can lead to severe burns, heart problems or loss of limbs or can even cause death.<\/p>\n

\"\"         \"\"<\/p>\n

\u2022 Contact injuries:<\/p>\n

This occurs when lightning strikes an object, such as a metal pole, that the victim is touching.<\/p>\n

\"\"<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n

\u2022 Currents in the ground:<\/p>\n\n\n\n

This occurs when lightning strikes the ground near a victim and the current travels from the impact site to the victim through the ground.<\/p>\n\n\n\n

What damage can occur in an installation without a lightning rod?<\/strong><\/p>\n\n\n\n

\"\"<\/p>\n\n\n\n

If the structure does not have a lightning rod, the lightning will normally hit the highest point of the structure and seek its way to earth in an uncontrolled way, through antennas, a concrete structure, pipes or cables. This passage of the current can cause breakage, sparks (which could lead to fire) and damage to people and equipment inside.<\/p>\n\n\n\n

The risks that the facilities may suffer directly or indirectly will be:<\/p>\n\n\n\n

Partial destruction of electronic equipment due to electric arc between metallic masses, partial or total destruction of electronic equipment due to high voltage supply, partial or total destruction of electronic equipment due to variable magnetic fields, partial or total destruction of electrical equipment and
electronics by high frequency radiation.<\/p>\n\n\n\n

The set of elements to intercept (air terminals), conduct (down conductors) and dissipate (grounding network) efficiently the lightning current.<\/p>\n\n\n\n

TERRAGAUSS ELECTROMAGNETIC LIGHTNING ROD SYSTEM<\/p>\n\n\n\n

The Terragauss electromagnetic lightning rod system is designed to prevent by 95% the probability of lightning strikes in a diameter of 160 meters, because it generates an electro-negative field that, due to the principle of repulsion of equal charges, prevents lightning from striking. within its protection area, for the remaining %5 it offers a safe dissipation path to ground, by offering a permanent resistance of less than 2 Ohms.<\/p>\n\n\n\n

The Terragauss electromagnetic system is patented before the IMPI (Mexican Institute of Industrial Property).<\/p>\n\n\n\n

FEATURES<\/strong><\/td>CONVENTIONAL AND\/OR FARADAY CAGE<\/strong><\/td>TERRAGAUSS<\/strong><\/td><\/tr>
Avoid atmospheric discharges<\/td>No, for not creating a cathode field.<\/td>Yes, it prevents the probability of lightning strikes by 95% in a protection level 1, in the negative electric field generated it repels the negatively charged clouds, since they have the same sign.<\/td><\/tr>
Guarantees permanent resistance less than 2 Ohms  <\/td>Doesn't<\/strong>, because the soils corrode due to the salts in the soil and the chemicals used, which reduces the amount of copper in the rods and consequently increases the ohmic resistance.  <\/td>Yes, <\/strong>because when coupling the metal structures, a resistance of less than 2 Ohms is guaranteed and it is permanent because the negative electric field generated considerably retards the effect of the galvanic couple and therefore corrosion.  <\/td><\/tr>
Radius of protection<\/td>Maximum 90 meters in diameter (depends on height)<\/td>160 meters in minimum diameter (regardless of height)<\/td><\/tr>
Requires interconnection<\/td>Yes, because all the points placed on the roof have to be joined and the electrodes of all the points must be interconnected.<\/td>No, since it is not necessary to interconnect, as 1 point is required, 1 single electrode in an area of \u200b\u200b160 meters in diameter<\/td><\/tr>
Events supported by a pararryos<\/td>An event<\/td>All events that occur during the warranty period<\/td><\/tr>
Reduces installation times<\/td>No, because it requires multiple lightning rod points, interconnection, with 2\/0 copper cable, lowering of the points to the rods with 2\/0 cable, rods, welding, etc., as well as the installation labor of the material and several holes for the rods.<\/td>Yes, when using a single tip, with a single descent to the electrode.<\/td><\/tr>
Operation in partially vandalized sites<\/td>No, since they only offer a single point of contact between the lightning rod and the physical earth, so when the cable is stolen, the system is disconnected from the system to earth, leaving the site at risk.<\/td>Yes, it offers a multi-grounded system that allows currents to be drained even in vandalized sites.<\/td><\/tr>
Reduce installation costs<\/td>No, because multiple lightning rod points are required, interconnection with 2\/0 copper cable, drops from the points to the rods with 2\/0 cable, rods, welding, etc. As well as the labor for installing the material and several pits for the rods.<\/td>Yes, when using a single point, with a single drop to the electrode in an area of \u200b\u200b160 meters in diameter.<\/td><\/tr>
Reduce vandalism<\/td>No, because they use more rods and cables, which are made of copper.<\/td>Yes, by using only 1 electrode and by using our galvanized steel cable solution, to connect the end to the grounding system, which is less attractive to be stolen than copper cable. Even without the cable that connects the coupler to the electrode, the system continues to drain the atmospheric discharges, until the cable is replaced.<\/td><\/tr>
Maintenance required<\/td>Yes, because they degrade due to oxidation, and require chemicals to be added to lower their resistance, but chemicals corrode rods that are made of steel with a hundredth of an inch of copper.<\/td>No, because they are made of copper, and by generating a cathodic field, the system slows down the corrosion effect by creating a permanent negative electric field.<\/td><\/tr>
10 years<\/td>No, no conventional land system offers guarantees.<\/td>Yes, it offers a 10-year written performance guarantee.<\/td><\/tr><\/tbody><\/table>
