Intelligent circuit breaker design and implementation for electrical current sensing and monitoring

Abstract

Electric shocks sustained when repairing power lines have been the main cause of the recent increase in electrical accidents involving linemen. Lack of communication between the maintenance staff and the electrical substation frequently leads to these events. A system utilizing the NodeMCU ESP8266 that enables remote control (ON/OFF) of electrical wires is suggested in order to improve linemen's safety. To turn the power supply on or off in this system, the lineman or maintenance personnel logs into the Blynk program.  In the event that an electrical line issue is identified, the lineman can use the Blynk app to turn off the power source, securely make the required repairs, and then turn the power back on.  LEDs are used to show the relay's ON/OFF status, and an LCD screen also shows it.  The lineman only needs to log out of the Blynk program after doing the work.
