This paper is about loss of electric energy in transmission line of both overhead and underground cable fault due to. So for increase reliability for electricity we make one underground and overhead cable fault detection circuit using internet of things. In this circuit internet of things device using detect the distance of fault in cable in form of line station and using Arduino microcontroller and showing result in webpage. In urban areas most of electric cable run in underground instead of overhead cable line. When the any fault in underground cable difficult to detect the location of fault. And very difficult to repair the fault of cable. Wide Variety fault of cable in underground condition, wear and tear ,rodents etc. its very difficult to detect the fault using all over underground line dug and find out fault of cable. Here we make cable fault detection to detect fault of cable over internet of things to make repairing work very easy. So repair men find easy way fault of cable and dug only faulty area. The system is detect fault by help of voltage divider circuit across the line of cable. When a fault is created at a point shorting two lines and open line fault a specific voltage is generated as per resistor networks. Voltage is sensed by microcontroller and given data to user. microcontroller retrieves the fault of cable data and displays over LCD display, also it transfers this data over a network to display in a web browser.

Arduino microcontroller, esp-01 wifi module, relay module , bridge rectifier, cable, voltage divider circuit.
