The project's goal is to create a device that can detect energy theft straight from the grid system. The primary issue facing our nation is energy theft straight from the main line. A lot of energy is tampered with, especially in rural areas, and our electricity department lacks the necessary instruments to pinpoint the exact location of the theft. Thus, the state electricity department is the beneficiary of this project activity. The idea behind the system is to measure the current flowing through energy transmission lines at sensitive areas, which are defined as locations where people use energy to run pump sets and where transmission lines pass very close to villages or over agricultural fields. Two CTs (current transformers) are used to measure the current in these locations. They are placed in series with phase, one on each side of the sensitive area. The current passing through the CT primary is now sent to the microcontroller in digital form. Since the current of two CTs needs to be measured—two distinct systems are built with two microcontroller units—the controller shows the current in amps. A master unit is one unit that is intended to be positioned at the beginning of a specific zone. The other device, which might be put at the other end of that specific zone, transmits the current through a digital signal. This data is received by the master unit and shown on the LCD. The data obtained remotely via the Zigbee network is compared with the output of the master CT, and the differences are shown in distinct rows. The system is set up so that when the difference is more than three to four percent, the alarm is activated automatically. The current flowing through both CTs is nearly equal, line loss is taken into account, and whenever energy is tapped between the two CTs, more current is passed through the first CT.
