Underground Line to Ground and Open Cable Fault Detection

Abstract

Underground cables are widely used due to the growing need for reliable electricity supply in cities. These cables are safe, and durable and improve the appearance of the city, but they are difficult and expensive to spot mistakes. Traditional methods include expensive devices that cause manual inspection or delays, high costs, and service disruptions. This project introduces a simple, inexpensive, and efficient way to identify line-to-ground and open circuit errors using an Arduino-based system. The system follows Ohm’s law and uses a low DC voltage for resistance to cables. If an error occurs, the voltage drops changes, and the Arduino microcontroller measures it to calculate the error distance. The exact location is displayed in real-time on the LCD screen, allowing for quick repairs without excavation. The system consists of an Arduino card, voltage sensor, resistor, relay, LCD, and power source. Software developed in the Arduino IDE handles changes in tension, finds errors, and shows results. Test setups are created to check the accuracy of the system under different error conditions. Using this system, power companies can improve repair duration, cost reductions, and service reliability. In contrast to traditional methods that require excavation, this system provides a non-invasive, fast, and accurate way to spot errors. It is also scalable and can be used in a variety of power networks. Future upgrades include IoT integration for remote monitoring, allowing maintenance teams to get real-time alerts. Machine learning can also help you predict possible errors. This allows for preventive maintenance and improved network reliability. This Arduino-based error recognition system is the latest effective and affordable solution. Future advances will help you build an intelligent, efficient, and sustainable power grid.
