UNDERGROUND CABLE FAULT DETECTION USING IoT

The proposed system is meant to solve the problem of accurately finding problems in underground cable lines, especially in cities where these lines are common. Using an Arduino microcontroller kit and a power source that has been connected, the system uses current measuring circuits that are connected to the microcontroller’s built-in Analog to Digital Convertors (ADC) device to get a precise reading of the wire length in kilometers. Switches are used to mimic faults, and relay circuit to controls the relays. A 16x2 Liquid Crystal Display (LCD) screen shows problem details in real time. The environmental possibilities like rain, underground pollution, drain leakage etc may cause short circuit faults in the underground cable. Various faults may occur in underground cable; this paper focuses on locating short circuit fault. The location of the short circuit fault is sensed as a voltage changes across the resistor and the distance is calculated from the source fed point and ADC digitizes it to display on the LCD. With the help of Wi-fi module 8266 the fault location details are stored in the cloud for further analysis. This lets the proposed Arduino microcontroller design to show exactly where the fault is (in kilometers) from the base station. A buzzer warning also lets field workers know that they need to take action right away if a fault happens. This novel method is a reliable and effective way to find and spot problems in buried cable lines. This makes servicing easier and cuts down on downtime.
