1.1 Lattice Steel Structures
The preferred method for installing grounds on higher voltage single-circuit lattice steel transmission line structures, where the conductors are a greater distance from the structure than those on lower voltage structures, is to install them from the bridge above the conductors(see Figure 2). On double-circuit lattic1.2 Slip Joint Steel Pole Structures
Slip joint structures either have bonding cables permanently attached to each joint or joint resistance should be measured on selected structures after installation and periodically as maintenance personnel deem necessary. Surfaces where protective grounds are to be attached must be cleaned prior to cable 1.3 Weathering Steel Pole Structures
The highly resistive protective oxideon weathered steel should not be removed. Protective grounding is best accomplished by welding a copper or steel bar or stainless steel nut to which a threaded copper stud can be inserted at each grounding location. Weathering steel poles should be constructed with bonds bSee more on electrical-engineering-portal d electric overhead line transmission steelPower Transmission & Distribution Online Training CoursesElectrical Power Distribution Training.
