The main concept of this project is to reduce the power theft by using an integrated energy meter such that whenever an energy meter is tampered, it sends an alert message to the concerned authorities through the GSM modem for indicating power theft.
Day by day increase in the usage of electricity is leading to several attempts of tempering the energy meter by the masses. The routine way of identification of tempered meters by the electricity department wherein – the department sends employees to check out this issue – is quite an expensive and time-consuming job. With this proposed system, it is possible to detect the meter tampering.
The proposed system uses a microcontroller of the 8051 family and a rectified power supply. In this system, the GSM modem interfaced to the microcontroller through a level shifter and a serial cable. A16*2 LCD display is connected to the microcontroller for displaying the information.
The energy meter is integrated in such a way that anybody opens the cover of the meter; an IR sensing arrangement sends commands to the microcontroller. Then the microcontroller gives the command to the GSM modem to send an SMS to the selected mobile number stored in the microcontroller by the program. This information also gets displayed on the LCD.
This project in future can be implemented by an added feature of disconnecting the supply to the load by electricity department through an SMS in case of any tampering attempt of the energy meter.
