Video of webinar "Creeping Plasma Channels Are the Main Reason for Decrease in Grounding Resistance in Lightning Current Flowing"

In the forthcoming webinar, we will consider how the grounding resistance varies due to lightning current. This is one of the main problems in the lightning protection. The grounding resistance determines the most essential part of the storm overvoltage, i.e. its resistive component. In order to estimate it, we should know a specific current value of the grounding resistance at a time and the given flowing current value.

A Video of a Rare Lightning Strike Will Show You a Feature You Did Not Know About!

Our VK group was contacted by a subscriber. His personal message contained a link to a video file noting that the event had happened quite recently. A short video has captured a lightning strike to a kindergarten. It seems to be an ordinary event but, when we had looked at it in details, we could not believe our eyes. Let us share this amazement with you.

Video of Webinar "How to Make a Very Bad Lightning Protection?"

The practical lightning protection has been existing for almost three centuries. During this time, reliable means and methods for protection against direct lightning strikes and hazardous effects of electromagnetic field have been selected and successfully tested. The engineers have obtained only the best tools. Then, what is this planned webinar about? Surely, this is not about what has been discarded during the operations experience. We are not going to present another criticism for active lightning protection although it probably could have been useful. We are talking about reliable protection means used by an unsavvy designer in other way than they were intended for.
