DESIGN AND IMPLEMENTATION OF ARDUINO BASED EMBEDDED SYSTEM FOR UNDERGROUND CABLE FAULT DETECTION

The extensive use of underground cables is because of the several advantages such as more secure than overhead lines, less susceptible to damage in adverse weather conditions, less expensive for shorter distance, environment friendly and low maintenance. However, it is difficult to locate the fault in underground cable. We have designed such embedded system which determines the distance of underground cable fault from the base station in kilometer. This system uses the standard concept of Ohm’s law at the feeder end trough cable lines. When the fault occurs then the voltage changes accordingly, which is given to the embedded system through ADC. The firmware of the systems processes the input signal and displays the faulty phase on LCD screen with the range in kilometer on computer scree
