DEVELOPMENT OF A SECURITY AND MONITORING SYSTEM FOR ELECTRICAL NETWORKS WITH LOCAL AND REMOTE CONTROL VIA ESP8266

This work presents the development of a security and monitoring system for 
electrical and electronic networks, using protection relays and the ESP8266 
microcontroller. The objective is to detect and prevent equipment failures, increasing 
reliability and reducing downtime. The solution enables both local and remote control: 
through a web-based interface, it is possible to check the status of each load, turn it on 
or off, and perform an emergency shutdown that deactivates all loads simultaneously. 
This approach allows for quick response in risk situations and supports operational 
continuity. The proposed architecture also enables predictive maintenance by providing 
real-time analysis of the load status. The results obtained demonstrate enhanced safety, 
greater system stability, and potential reduction in operational costs.
