At the present time, the majority of lightning protection methods are abased primarily on the interception and redirection of a lightning strike. Their operating principle is to create an environment in which the lightning strikes into a specially selected and designed lightning rod, after what the lightning current will be directed by down conductors into the ground and distributed in it with the help of the grounding device.
work scheme of classical lightning protection system
The key feature of these systems is that they do not neutralize, but only minimize the hazards of lightning.
The principle "prevention is better than dealing with the consequences" forced the engineers to create a system that can eliminate lightning development into the protected object. This system is called Dissipation Array System (DAS). DAS uses a phenomenon when a corona develops from sharply protruding structures subjected to a strong electric field caused by a thunderstorm cloud (we will call these structures "the receivers"). After the corona appears, it ionizes the surrounding air, thereby ensuring its own growth. When the growth reaches its critical rate, the corona goes into the streamer shape and generates a leader towards the cloud. Thus, the receiver discharges the lightning "on itself", as is the case of a classic lightning protection system.
