Password Based circuit breaker system is used with an android application. Due to increase in death of line mens working in electric area, we have come up with this innovation. This project does not allow to control of the circuit to be located in the working feild ensuring to minimisize the fatal accidents occuring with the line mens in the working field. The system’s control will be provided onli the line men working on that area in his substation. To make any repairs. the line men has to enter password using his android phone and switch OFF the circuit. This will help him work safely, do the required changes and after returing back to his substation he had to re-enter the password to switch ON. Since the control of the switches is in the hand of the line men itself, there is no chance of accidents occuring. This system provides the storage of password using EEPROM and also allows to change the password for security reason if and when required.
