Main Process Task of SDP

Main Process Task of SDP

Сommon use of electronics in smart technical devices makes us constantly keep in mind that microelectronic units have a low electrical strength. Many of them can be damaged by voltage lower than 1,000 V. Time of exposure to such voltage is not particularly important. Even several fractions of a microsecond are enough. Such surges are triggered by short-time current spikes of various origins, ...

Webinar of Professor E.M. Bazelyan Titled "Is An Isolated Lightning Protection Feasible Today?"

Isolated lightning protection is not a new thing. In the Russian regulatory documents, including Instructions RD 34.32.122-87, a concept of standalone lightning arresters has already existed. They were not installed on a protected facility but were spaced apart from it for a particular distance in the ground and air. Actually, these were isolated lightning arresters. Their task is to avoid lightning current distribution along metal structures of the protected facility and thus prevent damage to internal equipment and people's injuries.
