Proposing a Transient Model for H-Section Reinforced Concrete Power Poles

Accurate surge impedance measurement is critical in the field of electrical distribution and transmission towers. However, a majority of the studies that have been done so far, have focused on steel tower models, ignoring the common concrete equivalents. This work presents a novel approach to evaluate the electrical properties of H-section reinforced concrete power poles. The key parameters investigated include surge impedance, capacitance, and inductance, all crucial for transient analysis during lightning strikes. The suggested method is then rigorously verified with COMSOL Multiphysics in the following phase. The results demonstrate the substantial impact of material properties, particularly relative permittivity and electrical conductivity of the tower body, on surge impedance values. By bridging the gap in research concerning the transient behaviors of concrete towers, this research takes a major step toward the reliability of power systems infrastructures.
