Hi Santosh, Here's a video comparing Conventional Type Lightning Protection and ESE Type. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fbO-TAqB6X0.htmlsi=wCTHqyxCxwPnV5Ym
I have found your video very good and I will keep it as a reference. However, I have noted the following: at 1:01 you show a down conductor bolted to the wall. What is the voltage at that point when lightning strikes? Is it safe for the wall or any other component behind the wall? It may arc to other conductive surfaces behind the wall. How about a human being touching with the hand there while lightning strikes?
Hey Alberto, When lightning strikes, the voltage at the point where the down conductor is bolted to the wall can become extremely high. However, the wall itself typically remains safe due to the down conductor’s role in directing the lightning current safely to the ground. This is assuming the lightning protection system is properly installed and grounded. The potential issue arises if there are any conductive materials like rebars, electrical cables, or electronic devices behind or near the wall. These materials are at risk of experiencing a 'flashover' - an electrical arc caused by high voltage, which can lead to structural damage such as cracks in the wall or harm to electrical components nearby. In larger buildings with multiple down conductors, the risk of such events is mitigated. The reason is that the lightning current gets divided among multiple conductors, reducing the load and likelihood of flashover on any single conductor. Touching the down conductor during a lightning strike is highly inadvisable. It exposes a person to 'touch potential,' a dangerous condition where the human body can conduct electricity, posing serious hazards. It's important to note that lightning protection systems should always be installed by qualified professionals to ensure the highest level of safety and efficacy.
