Overhead distribution lines are susceptible to various issues that can lead to power outages:

• Vegetation Contact: Trees and branches growing into or falling onto lines are a leading cause of outages, especially during storms.

• Animal Interference: Squirrels, birds, and other wildlife can cause short circuits by contacting live parts.

• Lightning Strikes: Direct or indirect lightning strikes can damage equipment (transformers, surge arresters) and cause temporary or permanent faults.

• Equipment Failure: Aging components like transformers, insulators, or fuses can fail over time.

• Weather-Related Damage: High winds, heavy ice/snow loads, and extreme temperatures can cause conductor breakage, pole damage, or sag issues.

• Vehicle Accidents: Collisions with poles can cause significant damage and widespread outages.

• Overloading: Excess current on lines can lead to overheating and conductor damage. Regular inspections, proactive maintenance (including vegetation management), and the use of robust, high-quality equipment are crucial for minimizing these issues.
