Password Based Circuit Breaker with GSM Module

Abstract

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. When operated manually we see fatal electrical accidents to the line man are increasing during the electric line repair due to the lack of communication and coordination between the maintenance staff and the electric substation staff. In order to avoid such accidents ,this project designed to solve this problem by design breaker such that only authorized person can operate it with a password. The system is fully controlled by ATMEGA32 microcontroller. A keypad is used to enter the password to open or close the circuit breakers, which is indicated by a lamps. The global system for mobile (GSM) circuit enables remote control of the system. This leads to address the problem of loss of time. The system also provided protection against over current using the sensors.
