This document discusses methods for detecting and preventing power theft. It begins by outlining the problem of electricity theft in India, costing $17 billion annually. It then describes some common methods of theft, such as attaching magnets to meters or bypassing meters. The document presents a proposed circuit to detect two types of theft: phase bypassing and overloading. It includes block diagrams of the circuit and simulations of overload and phase bypass conditions. It concludes that the circuit can detect and instantly stop the supply in these theft situations, helping to reduce losses for electricity boards.
