Abstract
The aim of this project is to determine the distance of underground cable fault from base station
in kilometers. A constant current source feeds a known current into the wire under test (WUT). The voltage drop across the WUT is measured using the ADC. A short circuit is detected based on this difference voltage across the WUT. In case of a short circuit the length from the base station is calculated and displayed locally as well as informed to the user/admin through a SMS using a GSM modem. The length and the voltage across the WUT is also simultaneously uploaded to a ThingSpeak channel and if necessary further analysis can be done using MATLAB and can also be displayed using a user friendly UI.
