Underground Cable Fault distance Locator Electrical Project | Ver1

🧠 Project Overview – Underground Cable Fault Distance Locator

🚀 The Underground Cable Fault Distance Locator is an advanced electrical engineering project designed to detect and locate faults in underground power and telephone cables quickly and accurately.

This ready-to-use project uses a Varley loop circuit along with Arduino Uno, relay drivers, and a 16×2 LCD display to pinpoint the exact location of cable faults on Red, Yellow, and Blue lines. The fault distance is displayed directly on the LCD screen, making troubleshooting fast, safe, and efficient ⚡.

👉 Ideal for students of B.Tech, Diploma, Polytechnic, ITI, and hobbyists who want a real-world practical project with strong technical learning.

⚙️ How It Works & Core Components

🧠 The Arduino UNO controls the relays through a driver circuit. Each relay corresponds to one cable line. When a fault occurs, the Varley loop circuit detects the fault and sends the signal to the Arduino. It then calculates the distance of the fault and shows it on the LCD.

✅ Key Features:

• ⚡ Detects fault in multiple cable lines (Red, Yellow, Blue)

• 🖥️ Displays fault location on 16×2 LCD

• 🔁 Uses relay driver board for line selection

• 🔌 Powered by a reliable 12V 1A adapter

• 🪵 Mounted on a wooden board for safety and easy transport

✅ Core Components Used:

• 🟢 Arduino UNO

• 🔴 Borley Loop Circuit

• 🟡 Relay Driver Module (3 Relays)

• 🔵 16×2 LCD Display

• ⚡ 12V 1A Adapter

• 🧰 Wooden Base Board

• 🧠 Jumper Wires, PCB, Connectors

👉 All components work together to locate the cable fault precisely and display the exact distance for quick restoration.
