Abstract:
This circuit detects all the voltages and currents
from their respective transformers. According to the received voltages and
currents, power will be calculated. This method includes receiving data of the measured voltage
consumed by a plurality of customers, receiving delivered voltage that includes
data of the voltage delivered to the plurality of customers, determining a
difference between the receiving data and the maximum voltage, determining that
the receiving data is greater than a predetermined amount immediately an
electrical device will be turned off. If the receiving data is lesser than the
predetermined amount then it sends information to the substation that voltage is
low and a temperature sensor is used for sensing the transformer temperature.
If there exists an over temperature, then buzzer will give beep sound. Here, we
are using the GSM based wireless communication to send the information to the substation.
The programming language used for
developing the software to the microcontroller is Embedded/Assembly. The KEIL
cross compiler is used to edit, compile and debug this program. Here in our
application we are using AT89C51 microcontroller which is Flash Programmable
IC.AT represents the Atmel Corporation represents CMOS technology is used for
designing the IC. This IC is one of the versions of 8051.
