This UFC provides policy and design requirements for static electricity protection, and lightning protection systems and related grounding for facilities and other structures. . Recommendation ITU-T K. The need of protection is obtained from the methodology contained in IEC 62305-2, which is used to determine the relevant lightning protection. . Therefore, designing and implementing specialized wind turbine lightning protection solutions is not only a technical necessity to ensure normal equipment operation, but also key to reducing operational risks and maintenance costs. The mean radius re of this ring loop should be not less than l1, as indicated in Figure 1 and this value depends on. . How are base stations protected from lightning strikes? 1. GB 51120- English PDF Aug 31, GB 51120-:. . The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L). .
