Circuit Breaker with Password

Abstract

A circuit breaker is an electrical switch that operates automatically and protects an electrical circuit from overload or short circuit damage. Its primary function is to detect a fault and stop the flow of current. A circuit breaker, in contrast to a fuse, which only works once and must be replaced, can be reset manually or automatically to resume normal operation. During electric line repair, fatal electrical accidents involving linemen increase when operated manually due to a lack of coordination and communication between maintenance staff and electric substation staff. The breaker can be constructed in such a way that only an authorized individual can use it with a password to prevent such accidents. Changing the password can also be done in this location. The 8-bit microcontroller controls the entire system. Passwords are entered via a keypad, and a lamp indicates when a relay opens or closes the circuit breaker. A second lamp will indicate the activation of an alert in the event of a failed attempt to open the breaker by entering the incorrect password.
