The term ground systems is currently widely used due to the growing concern of protecting electric equipment failures and damages that are caused by a lack of these, however although it is a term used not all people understand its importance and its operation, due to this end up choosing an inefficient system that is worse in the long run ground or simply decide to not install anything for their teams.I.e. a grounding system are all the necessary elements for a proper reference to Earth. The physical Earth concept is applied directly to a third cable that must be connected to earth itself, or the ground, it connects into the third connector on outlets, these outlets are called polarized. relevance of the physical lands between the main functions to install a physical Earth system this offer protection in places where there is a ground operation consists in drain the ground currents of power created by short, induction or any discharge atmospheric, thus damaging electric power does not harm computers. Due to harmful downloads, it is common to detect electrical equipments and electronic problems as touches, short, failures, power outages, damage, high energy consumption and other situations that would not be provided with an adequate grounding system. Tierraprotegera connection system all equipment connected to an outlet of any overload that could originate and also will provide security and peace of mind to the inhabitants of the House.Benefits to installing physical land and lightning grounding system generates significant benefits that dramatically improve the quality of electric power, all this is reflected in the good performance of appliances and machinery, as well as numerous advantages such as:-reduction of accidents at work and home centres – diminishes the consumption of electrical energy.-increases efficiency and the useful lifetime in appliances.-reduces the heat generated in cables and motors in addition to the noise down considerably – take advantage of the input power to the electrical and electronic equipment, as well as compatibility and coupling between the sources of energy and electrical loads-earthing and lightning arrester system achieves the lightning fall in suitable places, avoiding that they damage buildings or people.-protect faults and malfunctions electromechanical equipment, maquinaria-herramientas, motors and controls-system significantly reduces the fault (s) generated by short circuit and shock, artificial or natural – minimizing the levels of interference and contamination between equipments, devices, components, accessories and human beings.Increases the quality of operation and balance ecologico.mejora the quality of the service, dissipates the current associated to atmospheric discharges and limited the envelope generated tensions.High efficiency tronica Mecca, (Automation, robotics, information technology.) The main relevance of implementing a land system physics and lightning rod It is to ensure the Centre’s work and housing where there are people which could be victims of an accident such as fire or claims which could be avoided with a system in ground system.
