Fault Detection in Transmission Line using Arduino Uno

Transmission line fault detection is a crucial aspect of maintaining a stable power supply. This paper presents a paper that uses Arduino Uno to detect faults in transmission lines. The system is designed to detect faults such as Line to Ground, Line to Line, Line to Line to Ground, and three phase fault. The fault detection system can quickly identify the type of fault and its distance (in km) & notify the maintenance team through an alarm (buzzer). The paper's implementation involved using the Arduino Uno microcontroller board, relay module, buzzer, transformer, voltage regulator, diode, resistor, capacitor, LCD Display, push button, jumper wires, plain PCB, breadboard, thermal sensor, potentiometer, bulb, holder. The relay module was used to switch the power supply of the transmission line on and off, while the buzzer was used to sound an alarm when a fault was detected. The results of this research indicate that the proposed system is an effective method for detecting transmission line faults. The system is simple, low-cost, and can be easily implemented. The fault detection system can help prevent power outages and reduce maintenance costs.
