Lightning protection system types7/2/2023 ![]() ![]() The distance between these two rods can be increased because they increase from the gap. The arrangement of these metal rods can be done around a small air gap. The types are Horn Gap ArrestersĪs the name suggests, this arrestor has two metal rods in horn-shaped. It provides a low resistance pathway to the surges in the direction of the ground. The construction of lightning arrestors is different based on its type but the working principle is the same. Generally, lightning arresters are classified into different types. Further, the current flow toward the ground will be stopped. Once the voltage of the system falls under the fixed value, then the insulation will be restored among the ground & conductor. So it will break down the insulation of the lightning arrestor for a moment, so voltage surge can be discharged toward the ground. Difficult to maintain (electrical continuity check, identification of the parts of the structure involved in the protection, etc.Lightning arrestor working principle is, once the voltage surge travels throughout the conductor then it reaches the location of the arrestor where it is installed.Simplification of the installation and reduction of costs.Protection by «natural» components Advantages The catenary wires can be a danger in handling areas where lifting equipment is used.Often not aesthetic due to the complexity of the structure.Contributes to overall equipotential between the conducting structures and ground.Spreading of lightning currents over several down conductors ![]()
