Review of N-Bundled Conductors on Right-of-Way in Transmission Network Reinforcement in Electrical Systems

Transmission line expansion has become one of the critical network planning strategies to ensure the continuous evacuation of power. Right-of-way (ROW) has posed significant challenges due to an increase in population and rural-urban development. This research therefore reviews various methodologies of investigating the effect of N-bundled conductors on right-of-way and power system parameters such as voltage, current, power and load. The review of technical literaturereveals that the effects of transmission lines bundling of conductors on the right-of-way were not considered in most cases of the literature reviewed. The changes in the electrical power system parameters with changes in conductor area and bundling of conductors were not examined in most cases of the papers reviewed. Eventhe relationship between transmission line expansion and bundling of conductors wasnot studied in most cases. To that effect, this study therefore proposed solutions to the above-mentioned shortcomings observed in the area of transmission network expansion.
