The external LPS is designed to intercept direct lightning strikes, conduct the current safely to the ground, and disperse it without causing thermal or mechanical damage to the structure. According to IEC 62305-3, an external LPS consists of three main elements: A. Air-Termination System
Connecting all internal metal installations, structural steel, and electrical/telecommunication lines to a main earthing busbar using conductors or Surge Protective Devices (SPDs). If you share with third parties, their policies apply
