What is bad about protection zones

What is bad about protection zones

  • 02.04.2019

The answer to this question can already be found from the written before. Suppose that the object is entirely located in the protection zone of a free-standing lightning rod, as shown in the figure. The height of the rod lightning arrester is h = 100 m, the lightning conductor ensures the reliability of protection P = 0.9, and, therefore, the probability of a lightning breakthrough to the object (Ppr = 1 - P) should not exceed 0.1.

What can be expected from laboratory tests of lightning rods

  • 18.03.2019

Such tests were started in the 30s of the past century. Air gaps 1-3 m long were used, then in the 60s they grew to 10 m, and several years ago the experiments were carried out with the length of air gaps of up to 30 m. As you see, it's an old story, and there is no task solution still. There is no unambiguous answer about the transfer rules of major experiments results to the real lightning. It's not surprising. A spark discharge in the gap op 10-30 m has much to do to the lightning channel kilometers long.
