Wire less power theft monitoring using gsm

Developing countries faces widespread theft of power from government owned power utilities. So the aim of this project is to display the power theft area of the distribution transformer and raise an alarm. Here for the practical purpose transformers, source energy meter, household load, energy meter are used for measuring real loads along with wired link.The power theft area of the distribution transformer at substation is obtained by calculating the real consuming power by the energy meter and the main power at the distribution transformer. That means the real consumption of all users must be equals to the total power delivered by the transformer. The difference must be analyzed by the controller by calculating both powers. If the difference is within 2 to 3% variation (transmission losses are concerned) the system raises no error otherwise it will generates error with an alarm and sends message along with transformer location information to the authority through GSM modem and displays in the corresponding substation along with alarm.
