Rarest Lightnings Captured from the International Space Station

Rarest Lightnings Captured from the International Space Station

What do "blue jet", "elf" and "red sprite" have in common? It appears that all of these strange names designate the phenomena associated with the lightning, which are very difficult to observe from the Earth's surface. To perform research of various atmospheric phenomena, in 2018, a set of optical cameras, photometers, and X-ray and gamma radiation detectors were installed at the International ...

Lightning Protection of a Water Tower in the Siberian Federal District

Lightning Protection of a Water Tower in the Siberian Federal District

A water tower seems to be a facility that, from the first sight, is not necessary to protect against lightning. The lightning protection is required not to protect the tower itself but to protect the equipment in the pumping room, with which a metal coupling exists along pipes or through the water. If a water tower is not protected against lightning, then the lightning current will go to the pumps along the pipeline and cause their failure.

Lightning Protection System for Observatory Located on Pip Ivan Mountain Using GALMAR Equipment

The astronomy and meteorology station on Pip Ivan Chornohora (the Carpathians) built by the Polish people in 1938 was not almost operated according to its intended purpose. For long time after the Second World War, there were only bare walls, and sometimes the building was used as a tourist shelter. Plans to reinstate the facility have regularly occurred since 1996. There was an information that ...

Lightning Protection of a Car Assembly Workshop

Lightning Protection of a Car Assembly Workshop

Sometimes, we have to protect really large facilities against lightning. A car assembly workshop having a total area over 50,000 sq. m was one of them. Although the grid can be installed on buildings with flat roofs, it does not provide protection against direct lightning strike. The customer did not like this lightning protection method, therefore, lightning rods were the only option.

Lightning Protection for 110 kV Electrical Substation

We have received a task to calculate the lightning protection for the 100 kV electrical substation with a closed switchgear (CSW). It is technically easier to protect it against lightning than the substation with an open switchgear since it has a smaller footprint, and the entire high-voltage equipment is located in the same building.

When Does the Orientation Process Start?

When Does the Orientation Process Start?

We have to start with a well-known fact. Lightnings never strike an on-ground structure. Its channel was always taken by the opposite leader. The longer it is, the more efficient the catch is. We will try to get maximum from this experimental fact, the more so since the lightning arrester operation experience allows providing a material quantitative clarification to the foregoing. A concentrated ...
