ABSTRACT
Underground cables are preferred to overhead cables due to less power loss, low risk of faults/damage, they are completely free from environmental changes and low maintenance costs. This makes underground cable systems very popular in major areas of metropolitan cities. Since the cable is underground when a fault does occur the repair process becomes difficult as the fault location is unknown. The focus of this chapter aims to locate the fault location from the base station and display it on a webpage over the Internet. Cable faults may arise because of these reasons: inconsistency, defect, weakness of the cable, insulation failure, and breaking of the conductor. Fault location can be communicated to the webpage using an IoT module. It sends the send data in graphical format. At the same time, the details are displayed on the LCD screen which is kept in the control room. Both open-circuit faults and short-circuit faults can be detected using this method. The entire service line is divided into sections based on distance and each section has a separate relay, so that whenever a fault occurs all the appliances connected to that line will be shut down. This will reduce the risk of electrical accidents. This method improves the accuracy of finding faults in underground cables and saves a whole lot of time in the repair process.
