Buildings and structures are more than meters above ground level and need to be equipped with lightning rods
In the near field has been equipped with a lightning rod of tall buildings, the protection angle of 70 degree within the protected object from the protected object, the highest point of the farthest point observation angle almost as high as small buildings in the open area of independent building or mountain building larger buildings can be used to increase the discharge needle or install multi needle to protect equipped with billboards and other facilities building installation location principle 1, after installation of lightning rod tip should be at the highest point of the building, floor and other equipment to avoid the distance of 1 meters above.
Suggest the need for 50 meters near the grounding resistance of high-voltage transmission line construction and installation of lightning rod 50 -100 meters high voltage transmission lines or substation near the control requirements of 50-100 meters 50 meters with grounding resistance near normal lightning tower control near normal lightning lightning with 20 meters tall buildings with 100 meters in 10 within Europe Normal Lightning communication tower with Europe in 10 (within the building, water tower and chimney etc.)
Select installation point, the lead should avoid 220 volt power line, telephone line, cable TV and other weak equipment, 3, select the installation point, you should choose the shortest location of the lead line. 4, select the installation point, should avoid living on top of the house. 5, in the construction of the existing lightning belt, directly in the vicinity of the lightning arrester grounding lead line installation. 6, if the roof surface area of more than 200 square meters, should be in the corner of the floor to install a lightning rod.
