Smart Underground Wireless Cable Fault Detection and Monitoring System

Whenever a fault occurs in the underground cable line for some reason, repairing wires of that faulty cable becomes quite difficult because of a lack of a proper system for tracking the precise fault location. A system needs to be developed that can find the precise location of the occurred fault in the system for all the three phases R, Y, and B for different types of faults conditions. By Ohm's Law, it is found that the resistance of the cable is proportional to its length under constant conditions of temperature and the cross-section area. Here a system is developed which consists of a microcontroller, LCD display, Fault Sensing Circuit Module, Wi-Fi Module, and proper power supply arrangement with regulated power output. Current in the circuit is sensed by the relays which are interconnected with the microcontroller. The fault sensing circuit is made with the combination of a set of series resistors and switches alongside each resistor. This proposed system is simulated and tested on PROTEUS version 8.1 and the hardware is designed on the basis of simulated design. In the end, the Fault is not only detected but also located at the exact location and has been shown on website “Things peak”.
