Analysis of the ground and lightning protection Abstract: With the modernization of social development, urban high-rise building, electronic information age, grounding and lightning protection system project has aroused people’s attention, it is important to protect lives and property measures is a grounding and lightning protection systems project, as long as construction in strict accordance with design specifications, use of good quality materials and equipment, in-depth and meticulous construction can achieve the desired results. Paper Keywords: grounding, lightning protection, captive power generation A grounding device Ground is a conductive surface of the object connected with the earth short, the body must have a valid ground to do a series of artificial grounding, grounding points ‘single grounding’ and ‘joint physical grounding.’ Monomer grounding and more used in a more independent entity, such as outdoor: the pole transformer, tower, civilian public electrical room, box transformer room, switch stations, cable branch box, cable termination, grounding lightning protection lines. Currently implements a conjoined ground network, referred to MEB grounding early as the International Electrotechnical Commission, IEC Standard 364-4-41 (1982) provides that the automatic power-off protection measures against indirect contact in the application of MEB, which includes PE busbar, grounding lines, water mains, the total gas pipes, heating and air conditioning risers and recommended construction of metal structures and between the metal pipe (other than natural human contacts, and then make the connection. MEB and other potential applications of the coupling, the anti- Ray, electric shock, shielding room, protection of buildings, electrical equipment, communications equipment and other play an effective role in protection. MEB, etc. are connected to be superior to other electrical grounding system, but the conditions were not difficult has been implemen
