Lightning Protection

Nature is unpredictable, as anyone not residents of St. Petersburg know it. Now it pleases you clear sunshine, and within fifteen minutes of sudden gusts of wind carry your favorite hat and pull out of the hands of a newspaper with which you are pleased rested on a bench in the park. And now the big drops of rain overtake you, running under a nearby canopy, and in the sky hear the thunder and the bright flash of lightning. Pinterest describes an additional similar source. Despite the well-known song about that, "There is no bad weather, troubles that accompany the rain, could be much worse blown hat. Lightning remains one of the most dangerous natural phenomena. Number of cottages and homesteads burnt due to lightning and very very much. Why do you wonder, because the lightning rod was invented long ago? The reason is that, for the inhabitants of megacities, the installation of such equipment in their own country house, it seems a complete nonsense.

When is it was to fry because of lightning strikes occurred? Yes, a million years ago. In the era of the dinosaurs or even earlier. I hasten to upset you – domestic and international experience clearly shows the facts out equipment failure with subsequent ignition in the absence of a comprehensive lightning protection system object. What kind of equipment is a receiver of electromagnetic energy of natural origin? The list can be endless, so we list only the main ones: antenna lines and cables, electricity lines and cables reception (transmission) of information management and signaling, motochnye products (transformers, inductors, etc.) Electric ground loops, conducting elements of structures, equipment. Now it becomes obvious the need for lightning protection, because these receivers in the house, each of us.

And, if the predicted weather patterns are not always Can even professional meteorologists, then protect yourself, your home and expensive equipment and technical progress allows us to happiness. To solve the above problem it is necessary: 1. To diagnose system supply buildings, including the definition of the type and configuration, the measurement of levels of power consumption at maximum load, short circuit currents in the opening of the switchgear and pulse characteristics of wires and cables in the building (in the microsecond range). Perform the necessary calculations and design work on the choice of the parameters of protective devices. 2. Set in the introductory switchgear equipment for the coarse limit overvoltages from direct or close lightning strikes. 3. Set in the floor distribution boards surge with a higher level of protection than that of claim 2. 4. Set in the most responsible consumers of computer and telecommunications networks protective device against distortions and failures in the transmission and processing.
