Abstract: The fault detection and alerting system for undersea and underground cable networks is designed to monitor, detect, and report faults in long-distance industrial cable infrastructures such as power and communication lines. These networks are critical yet difficult to access and maintain, making timely fault detection essential to prevent energy loss, data disruption, and costly downtime.

The proposed system employs a combination of IOT-based sensors, microcontrollers, and real-time data transmission to continuously monitor key parameters such as voltage, current, temperature, and insulation resistance. When abnormalities indicating potential faults such as short circuits, open circuits, or insulation failures are detected, the system intelligently locates the fault position and sends instant alerts through a wi-fi or gsm module to a centralized monitoring platform or mobile application.

This smart fault detection and alerting system enhances the reliability and safety of industrial cable networks, minimizes maintenance time, and reduces operational costs by enabling early fault identification and rapid response. The solution can be applied in submarine communication cables, underground power grids, and industrial data networks where continuous monitoring is crucial.Therefore, there is a need for an intelligent, automated system that can continuously monitor, detect, and locate faults accurately in real time and send instant alerts to maintenance personnel through wireless communication. The proposed intelligent fault detection and alerting system for undersea and underground industrial cable networks aims to address these challenges by integrating iot sensors, microcontrollers, and communication modules to provide efficient, reliable, and timely fault detection and reporting.
