Building lightning protection detection refers to the entire process of inspecting, measuring, discriminating, and comprehensively processing various information of lightning protection devices and facilities in buildings, crowded factories, flammable and explosive places, in accordance with relevant lightning protection technical standards, in accordance with prescribed procedures. Safety testing of building lightning protection devices is carried out in accordance with relevant national regulations. 1. Lightning arrester detection: The lightning arrester is an important lightning protection equipment that stores lightning rods, strips, nets, wires, and metals. Therefore, when conducting lightning protection detection on buildings, the lightning arrester is tested. Usually, the rolling ball method is used to calculate the protection range of the lightning rod and lightning wire, the grid method is used to determine the protection range of the lightning strip and net, and its grid size and laying method are tested, as well as whether the connection between the lightning strip and the down lead is closed. 2. Grounding resistance detection: Grounding resistance can effectively introduce lightning into the ground, avoiding electrification of buildings and causing harm to equipment and human bodies. Therefore, reputable lightning protection testing companies will test the grounding resistance of buildings, understand the layout of grounding devices, check the materials and specifications used for grounding devices, and then determine the service life of grounding devices based on these detection data. If the grounding device has been used for a long time or the selected material has poor corrosion resistance, a section of the grounding device will be selectively excavated during lightning protection testing, and more reasonable treatment measures will be taken based on the degree of corrosion of the material. 3. Detection of the working status of lightning protection devices: During the lightning protection detection process, the working status of lightning protection devices will also be checked, mainly detecting the lightning protection module of the power supply, lightning protection box, lightning protection socket, etc. In addition, the connection wire and grounding wire of the lightning protection device will also be tested to see the overall working status of the lightning protection device. 4. Conducting lightning protection testing on buildings is a necessary safety protection measure, as high-quality and reliable lightning protection equipment can provide good protection for the entire building and its occupants. Therefore, lightning protection testing must be carried out upon delivery and for a certain period of use, effective lightning protection testing must also be carried out to ensure the normal use of lightning arresters and grounding equipment.
