Introduction Transmission line towers are critical components of electrical power transmission systems. Their primary function is to support overhead conductors while maintaining required electrical clearances, mechanical strength, and system reliability. The selection of an appropriate transmission tower type depends largely on terrain conditions, line deviation angle, voltage level, span length, and mechanical loading. Utilities such
Abstract Extra High Voltage (EHV) 380 kV Overhead Transmission Lines (OHTL) form the backbone of modern power transmission systems, especially in the Kingdom of Saudi Arabia, where long transmission corridors and high power demand dominate network planning. One of the most critical operational challenges in long EHV OHTL is phase electrical unbalance, caused by the
