Electrical transmission line clearance refers to the practice of maintaining a safe and regulated distance between power lines and surrounding objects, most commonly trees and other vegetation. This is critical for several reasons: it prevents power outages caused by branches touching conductors, reduces the risk of wildfires initiated by electrical faults, and ensures the safety of the public and utility workers. Adhering to these clearance standards is essential for the reliability of the power grid and the prevention of catastrophic events.
