Electrical Engineering Lab: Transmission Line Experiment Analysis

This practical assignment details an electrical engineering experiment focused on transmission lines. The experiment investigates the Ferranti effect, voltage rise in lightly loaded transmission lines, and the characteristics of flat voltage profiles and linear phase shifts in lines loaded at surge impedance. The apparatus used includes a function generator, digital multimeter, oscilloscope, transmission line, and loads. The experiment covers open circuit tests, surge impedance load tests, and tests with loads above and below the surge impedance. Data is collected and analyzed to determine voltage profiles, phase angles, and delay times under various conditions. The results are presented in tables, graphs, and phasor diagrams, with comparisons made between single and double-length lines. The conclusion summarizes the key findings related to voltage behavior and the impact of line length and loading conditions. The assignment also discusses methods to restore receiving-end voltage.
