A lightning arrester is a device used to receive lightning and lightning, mainly composed of lightning rods, lightning strips, lightning wires, lightning grids, metal roofs, and metal components. The lightning protection detection of lightning arresters is an important project in the detection of lightning protection devices. The effectiveness of the lightning arrester directly affects the discharge effect of lightning current. So the step of lightning protection device testing is to carry out the testing of the lightning arrester. The 100% testing is to share with you the following testing requirements:
1. Testing
Testing is the testing during the construction process of lightning protection devices for new, renovated, and expanded buildings and the secondary testing after they are put into use. When testing the lightning arrester, it is necessary to check the records of concealed works and whether the roof facilities are within the range of direct lightning protection; The electrical connection between the lightning arrester and other exposed metal objects on the top of the building, the electrical connection between the lightning arrester and the down lead, and the equipotential connection of the roof facilities shall be checked as follows:
1. Whether the grid size of the lightning arrester network meets the requirements of the technical specifications, and the distance between the lightning arrester of the lightning protection building and the protected building, wind cap, vent pipe, etc. shall meet the requirements of the specifications 2. Use a theodolite or altimeter and a tape measure to measure the height and length of the lightning arrester, as well as the length, width, and height of the building, and calculate its protection range using the rolling ball method based on the lightning protection category of the building 3. Whether the materials, specifications, and dimensions of the lightning arrester comply with the technical specifications 4. Check if the installation position of the lightning arrester is correct
Function of testing report:
