Wireless Power Theft Monitoring System

The main objective of the project is to develop a wireless energy meter. Real-time Power monitoring at houses. Sensing the power theft. And transmitting the information over wireless to substation. By sensing current flow through the line & energy feedback we can prevent theft using a circuit breaker. In this system, a micro controller is interfaced with an energy metering circuit, current sensing circuit, RF communication link, & a contactor to make or break power line. At the sub-station end, a pc is connected with a RF link to communicate with all energy meters & a buzzer. In normal condition, micro controller reads energy pulses & current signals. If current is drawing & energy pulses are normal, then no power theft is being done & the output is connected. If current is drawing & energy pulses are not coming, then it indicates that power theft. So microcontroller trips the o/p using relay. The microcontroller takes the reading from the energy meter and displays the reading on the LCD. This project is powered by an on-board power supply takes the ac power and converts it into dc power that is fed to on-board devices and integrated circuits.
