A new article by professor Eduard Meerovich Bazelyan - “Underground utilities are dangerous when struck by lightning!” has been published on our website.
In the article, the professor describes the well-known problem of lightning current distribution in the soil. Despite the presence of multi-meter grounding electrodes, not all of the current goes into the ground; some goes to underground utilities: pipes, cable lines, and other components of the protected object. This puts people on the site as well as low-voltage electrical and electronic circuits in danger. Furthermore, even in well-conducting soils, the issue still exists.
The article provides a calculation scheme for estimating transported voltage, shows the results of computer modeling with a demonstration of the dependence of voltage delivered to the object via underground communication, and describes the peculiarities of works on extended communications in thunderstorm conditions.
