Password based circuit breaker using 8051

The project’s goal is to operate a circuit breaker alone with the use of a password. To enter the password, a keypad is attached to the project. Because of poor communication and coordination between the maintenance crew and the electric substation employees, fatal electrical mishaps involving linemen are becoming more common during electric line repairs. A solution that can guarantee the safety of the maintenance personnel, such as linemen, is offered by the proposed system. The line man alone is in charge of turning the line ON or OFF. This system is set up so that a password is needed to turn the circuit breaker on or off. When a lineman returns to the substation after comfortably fixing a problem, the supply can be turned back on.
