Introduction The global energy landscape is rapidly shifting toward renewable sources such as solar, wind, and hydro. While this transition reduces carbon emissions, it introduces significant challenges for transmission line design. Engineers must now account for variable loads, voltage fluctuations, and new grid stability requirements. Proper planning ensures safe and efficient transmission networks for a
Introduction Transmission lines form the backbone of modern power networks, stretching across cities, rural landscapes, mountains, and even waterways. While these high-voltage lines are essential for delivering electricity, their height and long spans also make them potential hazards for air and ground traffic. To address this challenge, engineers employ obstruction marking and lighting systems—a combination
