Design Implementation and Evaluation of Password Protected Circuit Breaker for Reliable Power System Protection and Maintenance

Password-based circuit breaker is a blueprint that empowers us in controlling the electrical lines with the help of password. This project gives this problem to ensure line safety. In this project, the schedule is done along these lines that the lineman is free to control the electrical line by entering the password to ON/OFF the electrical line. To achieve this, we have made use of PIC16F877A microcontroller. This microcontroller is one of the most eminent microcontrollers because of its flash memory technology which makes the write–erase process done as many times as possible. Also this plays a major role in digital electronic circuits. To develop the password-based circuit breaker to reduce the number of accidents to linemen in their working field, lineman has to do the task by turning ON/OFF.
