Kit Components Explanation
Conclusion and Future scope
The project is designed to trip the circuit with the help of
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
The TRIAC is a three
device for controlling
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
Keypads 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.
LCDs are the most widely used output devices of the
LCD stands for Liquid Crystal Display.
LCD is finding wide spread use replacing LEDs.
They are used for writing different messages on a
It avoids the electrical accidents.
Improves lineman safety.
Easy of operation.
Easy to maintain and repair.
Can be used any where in the substation to trip the
Most useful to operate in the public areas.
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.
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.
