Password Based Circuit Breaker is a simple system that helps in controlling the electrical 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 system 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 system is arranged in such a way that maintenance staff or

ATMEGA328P is high performance, low power controller from Microchip. ATMEGA328P is an 8- bit microcontroller based on AVR RISC architecture. It is the most popular of all AVR controllers as it is used in ARDUINO boards.

How to Use ATMEGA328P

ATMEGA328 is used similar to any other controller. All there to do is programming. Controller simply executes the program provided by us at any instant. Without programming controller simply stays put without doing anything.


A time switch (also called a timer switch, or simply timer) is a timer that operates an electric switch controlled by the timing mechanism.

Intermatic introduced its first time switch in 1945, which was used for "electric signs, store window lighting, apartment hall lights, stokers, and oil and gas burners." A consumer version was added in 1952.

The switch may be connected to an electric circuit operating from mains power, including via a relay line man has to enter the password to ON/OFF the electrical line Now, if there is any fault in electrical line, then the 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. Separate passwords are assigned for each electrical lines with the help of a password.


This system describes a technique of adding the remote control feature to an electrical appliance. The goal is to construct a black box where you can plug in your Ac appliances and control the ON and OFF operations with a TV or DVD remote that uses modulated infra-red (IR) pulse train of 38KHz frequency. The good thing about this system is that it

does not use any microcontroller and is only based on the CD4017 decade counter IC. Specifications of components

As said, first we need to program the controller and that is done by writing the appropriate program file in the ATMEGA328P FLASH memory. After dumping this program code, the controller executes this code and provides appropriate response.

Entire process of using an ATMEGA328P goeslike this:

Burn the HEX file of written program in ATMEGA328P flash memory using this


Disconnect the programmer, connect the appropriate peripherals for the controller and get the system started or contactor; or low voltage, including battery- operated equipment in vehicles. It may be built into power circuits (as with a central heating or water heater timer), plugged into a wall outlet with equipment plugged into the timer instead of directly into the power point; or built into equipment.

The timer may switch equipment on, off, or both, at a preset time or times, after a preset interval, or cyclically. A countdown time switch switches power, usually off, after a preset time. A cyclical timer switches equipment both on and off at preset times over a period, then repeats the cycle; the period is usually 24 hours or 7 days.

Time switches can be used for many purposes, including saving electric energy by consuming it only when required, switching equipment on, off, or both at times required by some process, and home security (for example switching lights in a pattern that gives the impression that premises are attended) to reduce the likelihood of burglary or prowling.

Among applications are lighting (interior, exterior, and street lighting), cooking devices such as ovens, washing machines, and heating and cooling of buildings and vehicles.[3] Built-in automatic washing machine controllers are examples of very complex electromechanical and electronic timers cycles, starting and stopping many processes including pumps and valves to fill and empty the drum with water, heating, and rotating at different speeds, with differen combinations of settings for different fabrics.

The output of first timer is connected to 230v primary side of step-down transformer, it is center tap transformer, of 1 A current rating.

The secondary 12v AC of transformer is connected to bridge wave rectifier

The output of rectifier circuit is connected to 8th Vcc pin of 555 timer ic .8th and 4rth reset pin of ic are shorted together. For provide the time delay to relay we used 555timmer ic and connected the 100k ohm resistor and 47micro F capacitor to the ic for providing 0 time delay. The output of ic is taken from pin no. 3 and connected to the relay coilterminals ic and 440v AC supply is given to common pin of both the relays we shorted the common pin and No pin of relay 1 initially .so that when supply is given to the relay common pin is shift to normally close pin from normally open andcontinues the couple further. The same connections are done for the 2nd off timer also but shorted common pin and NC pin of relay 2 are
