The project is designed to control a circuit breaker by using a password for the safety of electric man. Critical electrical accidents to line men are on the rise during  electric line repair due to lack of communication and co-ordination between the maintenance staff and electric substation staff.

This proposed system provides a solution that ensures  safety of maintenance staff, i.e., line man. The control to turn on/off the line will be maintained by the line man only because this system has an arrangement such that a password is required to operate the circuit breaker (on/off).

This system is fully controlled by a microcontroller from the 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. The activation / deactivation of the circuit breaker is indicated by a lamp that turns on or off.

Furthermore, this project in future can be enhanced by using EEPROM, for the user to change the password for  more secured system interaction. It can also be interfaced with a GSM modem for remotely controlling the circuit breaker via SMS.

Easy to use, Self-explanatory kit.

I just got to know about edgefx through google. The keywords i used to find the project was Engineering final year projects.
I have decided to buy project from edgefx because cost is less. Project implementation was good. I like most about edgefx was the Presentation of project.
Yes, kit was delivered on time with right components.
the customer service has helped me purchasing the project.
I would like to give reference to my juniors.
