- 4. ABSTRACT 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 coordination 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 an arduino. A matrix keypad is interfaced to the arduino to enter the password. The entered password is compared with the password stored in the ROM of the arduino. If the password entered is correct, then only the line can be turned ON/OFF. Activation / deactivation of the circuit breaker are indicated by a lamp (ON/OFF).We can change the password after every time we use the system to increase the security level of system. A unique password should be known to some responsible person of the staff only. 4

INTRODUCTION Nowadays, electrical accidents to the line man are increasing, while repairing the electrical lines due to the lack of communication between the electrical substation and maintenance staff. This project gives a solution to this problem to ensure line man safety. In this proposed system the control (ON/OFF) of the electrical lines lies with line man. This project is arranged in such a way that maintenance staff or line man has to enter the password to ON/OFF the electrical line. Now if there is any fault in electrical line then line man will switch off the power supply to the line by entering password and comfortably repair the electrical line, and after coming to the substation line man switch on the supply to the particular line by entering the password. The relay ON/OFF operation will be indicated by the LED’s; also it sends a message to the receiver about the line disconnection. As soon as the maintenance work is finished then line man should enter the same password as used to disconnect the line earlier. Advantages: • Save the life of line man. • User friendly operation of main line. • Easy to install and operate & cost effective. • Easy to maintain and repair

- 8. DETAIL EXPLANATION OF THE COMPONENTS 8 1. ARDUINO – Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.
- 9. DETAIL EXPLANATION OF THE COMPONENTS 9 2. A 4x4 matrix keypad is used to input data and send it to the Arduino. It has 16 keys arranged in a grid of four rows and four columns. To interface the keypad with the Arduino, the rows and columns are connected to digital input/output pins on the Arduino. The rows are connected to the output pins, while the columns are connected to the input pins. The Arduino reads the input by scanning the columns one by one and checking the state of the rows. When a key is pressed, the Arduino detects the row and column and maps it to the corresponding key. 4x4 MATRIX KEYPAD -

They are very usefully device and allow one circuit to switch another one while they are completed separated. The required current to run the relay coil is more than can be supplied by various integrated circuits like operation amplifier, etc. RELAY -

- 13. RESULT 13 • WHEN THE CIRCUIT IS POWERED ON, IT ASKS FOR PASSWORD, ONE CAN SEE ON THE SERIAL MONITOR (SERIAL MONITOR IS NOT MANDATORY BUT, CAN BE USED FOR TESTING PURPOSE). • ENTER THE PASSWORD WHICH YOU ENTERED IN THE PROGRAM BEFORE COMPILING IT. • WHILE YOU PRESS THE KEYS, GREEN LED BLINKS FOR ONE TENTH OF A SECOND, INDICATING THAT SOME KEY IS PRESSED BY THE USER. • ONCE YOU ENTERED THE 6-DIGIT PASSWORD, PRESS ‘D’ IN THE KEYPAD WHICH ACTS AS ‘ENTER’. • IF YOUR PASSWORD IS CORRECT, THE RELAY GETS ACTIVATED, GREEN LED TURNS ON.
- 14. APPLICATIONS 14 HOME SECURITY SYSTEMS: • A password-based circuit breaker can be used in home security to prevent unauthorized access to the system. ACCESS CONTROL SYSTEMS: • A password-based circuit breaker can be used in access control systems to restrict access to a building , office &restricted area. INDUSTRIAL CONTROL SYSTEMS: • A password-based circuit breaker can be used in industrial control systems to prevent unauthorized access to sensitive equipment and data.
- 15. CONCLUSION 15 It can work on a single given known password. The password to operate can be changed and system can be operated efficiently with the changed password. No other person can reclose the breaker once the changed password is given into system other than the person who had changed it. It gives no scope of password stealing. It is effective in providing safety to the working staff. It is economical. It can be easily installed.
