The
project is designed to control a circuit breaker with help of a password only.
A keypad is connected to the project to enter the password. Fatal electrical
accidents to the line man are increasing during the electric line repair due to
the lack of communication and co-ordination between the maintenance staff and
the electric substation staff.
This
proposed system provides a solution, which can ensure the safety of the
maintenance staff e.g. line man. The control to turn ON/OFF the line lies with
the line man only. This system has an arrangement such that a password is
required to operate the circuit breaker (ON/OFF). Line man can turn off the
supply and comfortably repair it, and return to the substation, then turn on
the line by entering the correct password.
The
system is fully controlled by a microcontroller from 8051 family. A matrix
keypad is interfaced to the microcontroller to enter the password. The entered
password is compared with the password stored in the ROM of the
microcontroller. If the password entered is correct, then only the line can be
turned ON/OFF. Activation / deactivation of the circuit breaker is indicated by
a lamp (ON/OFF).
Further
the project can be enhanced by using an EEPROM for user to change the password
for a more secured system. It can also be interfaced with a GSM modem for
remotely controlling the circuit breaker via SMS.
