MAIN OBJECTIVE
The project is designed to trip the circuit with the help of a password.
This control system provides a solution , which can ensure the safety of line man.
The system is fully controlled by the 8052 microcontroller (where password is saved initially)and by an IC.

TRIACThe TRIAC is a three
terminal semiconductor device for controlling current.
It is effectively a development of the SCR or thyristor, but unlike the thyristor which is only able to conduct in one direction, the TRIAC is a bidirectional device.

KEYPADKeypads are the most widely used input devices of the
8052and a basic understanding of them is essential. The keypads are mainly three types:
1) 4*3 keypad 2) 4*4 keypad
3) 4*8 keypad. The keypad used in this project is 4*3 keypad.

LCD DISPLAY
LCDs are the most widely used output devices of the 8052.
LCD stands for Liquid Crystal Display.LCD is finding wide spread use replacing LEDs.They are used for writing different messages on a
miniature LCD.

ADVANTAGES It avoids the electrical accidents. Improves lineman safety. Easy of operation. Easy to maintain and repair.
APPLICATIONS Can be used any where in the substation to trip
the circuit. Most useful to operate in the public areas.

CONCLUSION
Security is prime concern in our day-to-day life. Every one wants to be as much as secure as to be possible.
This system provides a new approach to secure the life of a lineman.
The circuit can be tripped without any fail and load can also be controlled when required.

FUTURE SCOPE
The project can be interfaced with the GSM modem for the remote control of circuit breaker via SMS. So the circuit breaker can, not only operate from the substation, but also from distance through wireless communication.
SCADA can also be implemented to know where
the fault is occurred in the system directly and so a linemen can directly locate the fault location and can rectify it.
