When there is a thunderstorm, it is advisable to turn off and unplug equipment (including antennas and equipment connecting the pan) to avoid lightning from entering the electrical system, causing damage and complete paralysis of electrical machinery (electronic ; avoid standing near doors, walls, wet areas, ponds, etc.<\/span><\/p>\n<p><span style=\"color: #000000;\">Lightning poles are usually placed on the roof at a high position and are led directly to the grounding system by the lightning conductor.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span id=\"De_lam_cot_chong_set_can_chu_y_may_diem_sau\">To make a lightning arrester, it is necessary to pay attention to the following points:<\/span><\/h2>\n<p><span style=\"color: #000000;\">\u2013 Lightning arrrester needs to be installed in a high position to increase the protection range.
