Why is it important to use bird guards and deterrents on overhead transmission lines?
2025-08-12The use of bird guards and deterrents is critical for maintaining the reliability and safety of power systems. Birds, especially large raptors, often perch and nest on transmission towers. This activity can lead to several problems:
-
Electrocution: A bird can complete an electrical circuit by simultaneously touching two energized conductors or an energized conductor and a grounded part of the tower. This not only results in bird mortality but also causes power outages and potential damage to equipment.
-
"Streamer" Faults: Bird droppings (streamers) are highly conductive and can bridge the gap between energized and grounded parts, causing flashovers and short circuits. This is a common cause of unexpected power failures.
-
Nesting Material: Birds building nests on insulators or other critical components can introduce foreign conductive materials that compromise the integrity of the electrical system, leading to faults and fires.
By installing high-quality, purpose-built bird guards and deterrents, we ensure the safety of wildlife while simultaneously protecting the power grid from costly outages and maintenance issues.
