Underground Cable Fault Detection Using Raspberry PI

Under Ground Cable Fault Detection:

The aim of this project is to determine the distance of underground cable fault from base station in kilometers. This project uses the simple concept of ohm’s law.When any fault like short circuit occurs, voltage drop will vary depending on the length of fault in cable,since the current varies. A set of resistors are therefore used to represent the cable and a dc voltage is fed at one end and the fault is detected by detecting the change in voltage using a analog to voltage converter and a microcontroller is used to make the necessary calculations

IRD INDIA Concept Prototype

IOT Concept:

PI Detects the Faults via a Circuitry, Process it and finds the distance of the Fault in KM. Update the Server via TCP/IP Protocol, Firmware Implementation is done Using Python and it communicates to the server with IP and port number. Server side Code is Implemented using LabView which is a Graphical Programming Test and Measurement Tool which Indicates the Fault Location using GUI.
This Project requires active Internet connection or atleast the Network where PI and PC running Labview Application are connected.
