FOUND FOR YOU: crack
walls, roof trusses go Flame on, all the facades are blown away: The damage from a lightning strike can be devastating. Much more frequently than the building but the electronics are drawn in the house affected.
flows in a flash power with a voltage of tens of millions of volts, and in the flash train, it is up to 30,000 degrees Celsius - that's five times the temperature on the solar surface. In 2007 alone, insurance companies have settled in Germany, according to the Confederation of the German insurance industry lightning surge damage of around 300 million €. Nevertheless, the human being this "celestial power" to not completely defenseless.
Protect from outside
against a "hit" lightning rod help. They reflect the fact that the electrical energy between clouds and ground searches the shortest route. Therefore, the fishing facilities at the highest points of the building, mounted the classic single-family house that is on First or chimney. They are made of metal, which conducts better than the fabric of the building. The lightning rod and the Ableiteranlage can not rust and need to be solid enough to safely dissipate the electrical energy without melting it.
flows through the arrester from the energy in the earth and from there into the ground. It is often used to the foundation ground, to which the cable system of the entire house is already connected. If the ground resistance is too high because of special soil conditions, it may be necessary to install additional grounding of metal.
shock from the line
The flash can also take the detour via the power grid and power outlet. Power poles and transmission lines are indeed protected from impacts, but this is not one hundred percent certainty. As more and more, always more complicated and more expensive electronics in the home occurs, protection against shock from the line becomes more important. The simplest method: pull the plug. Also, the antenna connector on the TV and the phone should unplugged during lightning storms be. Less sensitive equipment such as a coffee maker need not necessarily take the grid. Who wants to spend money for lightning protection, trading takes place in different technical solutions. Relatively cheap, but only limited life, are switched off power strips with surge protection. You should pay attention to the quality of the bar that is certified as the VDE certification. Similar interposer connector is available for telephone and wall outlets. Strong tensions may be felt among these components.
backup power for electrical appliances
a higher level of security offered by installed surge protection in the entire house, from the a professional firm must be installed. If the electronics are also against the frequent power surges is immune to follow the power-performance devices in the home, such as the circular saw in the hobby room.
The cost for such a move permanent installation for a house 500-2000 €. The difference is explained by the wide range from a basic protection to a reconstruction, which includes shielding all metal parts and wires and additional protective equipment in individual rooms. The third and most difficult warring source of damage is the electromagnetic pulse (EMP), the electromagnetic field that builds up around the lightning channel around. It is directed to several hundred meters Distance damage to electronics, he needs without a conductive connection. The normal surge protection can only limit damage to EMP, but it helps little to impact in the immediate vicinity of the house. Although there are methods of protection against this form of prejudice, but it would mean for ordinary houses an oversized effort.
