This document describes a wireless electricity theft detection system using Zigbee technology. The system consists of a transmitter side and receiver side connected by Zigbee modules. On the transmitter side, current transformers are connected to the load and monitor the current. If theft is detected, based on abnormal current readings, a signal is sent via the Zigbee transmitter to the receiver. On the receiver side, the signal is received by the Zigbee receiver and relay and buzzer are activated to alert the user of theft. The system is designed to overcome issues with previous wired techniques by enabling wireless monitoring and detection of theft as well as identifying tampered areas. It aims to help reduce electricity losses due to theft.
