Abstract

This paper deals with fabrication of an IoT device intended to detect the distance of fault in cable lines from the base station using an Arduino micro controller kit and display the result through a web page. In the urban areas, the electrical cable runs in undergrounds instead of overhead lines. Whenever the fault occurs in underground cable it is difficult to detect the exact location of the fault for process of repairing that particular cable. The Cables are prone to a wide variety of faults due to underground conditions, wear and tear, rodents etc. The repairmen know exactly which part has fault and only that area is to be dug to detect the fault source. The system detects fault with the help of potential divider network laid across the cable. Whenever a fault gets created at a point shorting two lines together, a specific voltage gets generated as per the resistors network combination. This voltage is sensed by the microcontroller and is updated to the user. The information conveyed to the user is the distance to which that voltage corresponds to. The microcontroller retrieves the fault line data and displays over LCD display, also it transfers this data over a network to display in a web browser.
