Ferranti Effect on a T- Section Model of an Overhead Transmission Line – A detailed Analysis

This paper presents a novel laboratory model designed for hands-on evaluation of the Ferranti Effect on transmission lines. The Ferranti Effect is characterized by a steady voltage at the open end of an uncompensated transmission line that surpasses the voltage at the sending end. The key aspect of this research lies in its empirical approach, achieved through experimentation using hardware equipped with a power generator and an advanced double bus bar system. The experimental analysis focuses on voltage regulation and the observation of voltage profiles on transmission lines. The study aims to identify the capacitive and inductive properties of the line as crucial factors in the manifestation of the Ferranti Effect, particularly under conditions of light load or open circuits at the receiving end. By doing so, it enhances the practical understanding of transmission line phenomena. This empirical investigation offers valuable insights for power engineering education, emphasizing the significance of laboratory prototypes in validating theoretical concepts.
