What is surge protection?prenapetost
In industrial and commercial buildings as well as in residential houses is now accumulated a lot of electronic equipment, which is very sensitive to surges. Even where regulations do not explicitly require the installation of adequate protection, this does not justify a designer that does not comply with these requirements, especially when considering that today's technology to offer an adequate level of protection devices. If a failure occurs and the destruction caused by lightning, this is the fault of the developer, who could not find an appropriate solution, or an investor who is spared in the wrong place. Few sources of energy surges is so strong that they are the right measures can not be tamed.

Causes of overvoltagessurge-protection

Surges that come to the consumer, may be due to switching in the power system (on and off appliances, turn short circuits) or the result of lightning, and risk of customer directly (direct lightning strike to a facility or energy line), or indirectly as from the effects of electromagnetic fields generated by lightning (distant lightning).

Lightning protection is not the subject of this article, but it must be noted, however, because of surge protection are closely linked. Lightning protection to protect the outside of your building from fire and mechanical damage (explosion due to evaporation, electrodynamic forces), the inner part of protecting the installations and of course above all people. The basic measure of internal lightning protection potential equalization, which

This is not dangerous to humans because of potential equalization in the same, although a high
