IoT Based Under Ground Cable Fault Detection with Cloud Storage

Determining the origin of the fault presents a challenge, necessitating the complete removal of the cable from the ground for thorough inspection and repair of any faults. The fundamental concept involves the utilization of a subunit to remotely measure the voltage. Hence, the fault is detected by utilizing the secondary unit. This implementation utilizes three sub-units within a transmission line and employs a switch to establish the transmission line. In the event of a fault, subsequent slave units will be unable to update their status. The error will occur between the specified point and the subsequent secondary unit. The status of all units within a shared Internet of Things (IoT) application can be accessed globally from any location. In order to identify a fault in a cable, it is necessary to conduct a fault test on the cable. This test involves utilizing a series of switches positioned at predetermined intervals along the cable's length to induce the occurrence of the fault. The communication link is established between two substations. During a fault occurrence, the voltage experiences a decrease and subsequent fluctuations. This altered voltage is then transmitted to the ESP32 device that has been programmed accordingly. The ESP32 device then proceeds to exhibit the received information on the LCD screen. The Internet of Things (IoT) utilizes the ESP32 Wi-Fi module to transmit and present data over the internet. The website is developed utilizing HTML coding, and it presents information regarding fault occurrences. Alternatively, users may opt to utilize an Android application for accessing this information.
