Password Based Circuit Breaker

Published on 20 May 2022. Written by Karthy R

The circuit Breakers one of the most essential part used in electrical system. The circuit breakers are plays an important in the field it prevents the fault switch and prevents the instruments from the sudden changes from on the line.

In Substation, Circuit breakers are used to switch the topology of the power system to accommodate various configuration for routing the loads. At the same time circuit breakers are used to isolate the fault area. The fault has to be rectifies by the line man of the substation. For that the engineer should turn of the main and to rectify the fault area. During the time someone is switched on the line pass through damage the instruments as well the engineer.

So prevention based thinking why we can put the lock or password to between the main and circuit breaker?

You need the 8051 family microcontroller (i.e.AT89s52), Relays, Load, Power supply, Keypad. And You need to program like when the password is enter on the keypad controller checks it and the matched means on the main line should be connected to the load via the relay. So the corresponding engineer while working the fault area by using the keypad password to block the main supply, when fault is cleared the password entered matches the power is supply through the circuit breaker. It avoid the unwanted accident issues can be prevented.

These kind of prevention is implemented even industries, residual homes also.

Project Description:

AT89S52: The AT89S52 is a low power, high performance CMOS 8-bit microcontroller with 8k bytes of in-system programmable flash memory. This is a powerful microcontroller which provides high flexibility and cost effective solution to many embedded control applications. It has the following standard features: 8K bytes of flash, 256 bytes of RAM, 32 I/O lines, watchdog timer, 2 data pointers, 3 16-bit timers/counters, on-chip oscillator and clock circuitry.
Relays: A relay is an electrically operated switch.It can handles the high power required to directly control an elecric motro or other loadas is called relay or contactor
Keypad: The pushbutton is used for the keypad inputs to the microcontroller(i.e. password)

Project Brief: The Engineer first enter pass to shut the power to circuit breaker,then fault clear,reenter the password matched the power is applied through relay to the loads.
