abstract = {Underground cable systems play a crucial role in modern power distribution due to their advantages such as improved safety, reduced transmission losses, and minimal exposure to environmental disturbances compared to overhead lines. However, locating faults in underground cables is a complex and time-consuming task because the cables are not visible and traditional fault detection methods often require extensive manual effort and specialized equipment. To address these challenges, this project presents the design and implementation of a microcontroller-based underground cable fault detection system that offers a simple, cost-effective, and efficient solution.
The proposed system is capable of detecting faults in all three phases (R, S, and T) of an underground cable and determining the fault location by calculating the distance from the supply end. The system operates on fundamental electrical principles, where variations in voltage and resistance caused by faults are analyzed to estimate the fault distance. The calculated distance and the corresponding faulty phase are displayed in real time on an LCD screen, enabling quick and accurate fault identification.},
