Abstract

This Project is required to discover the situation of fault in underground cable lines from the bottom station to the exact location in kilometer with the help of PIC Microcontroller (PIC18f877a). In the geographical area the line runs in underground rather than overhead lines. Whenever the fault occurs in underground cable it is hard to discover the exact location of the fault for repairing that cable. The projected system finds precise location of faults. This system uses PIC Microcontroller and regulated power supply. Here the present sensing circuits are

created with a set of resistors unit interfaced to PIC Microcontroller in order to assist of the ADC to provide digital signals to the microcontroller representing the length of cable in kilometers. The occurrence of fault is made by using the set of resistors of 1kilo ohm. The relays are controlled by the relay driver IC (ULN2003A). A LCD display is connected to the microcontroller to display the Fault. In case of fault, the voltage across resistors changes accordingly and that change in voltage is fed to ADC to develop precise digital value from base station in kilometers. GSM SIM-800 is additionally connected to the PIC Microcontroller and it discovers the fault and send SMS on the user’s mobile.
