This document summarizes an advanced metering infrastructure system that detects electricity theft. It consists of two current sensors, one to measure the current supplied from the distribution box and one to measure the current consumed by the home. An Arduino processor compares the current readings and if a difference is detected above a threshold, it cuts power to the home and sends an alert message via GSM to the nearest substation. The system aims to reduce electricity theft by automatically detecting the location of theft and notifying authorities to reduce losses for power suppliers.
