This document describes a technique to prevent power theft using a static device. It aims to control voltage across a load by monitoring incoming voltage and calculating firing angles for a TRIAC. The system includes a microcontroller, zero crossing detector, TRIAC, driver circuit, and potential transformer. It can provide a constant output voltage between 210-240V even if the input voltage varies from 230-300V. For illegal consumers using banned hooks or bypassing the meter, it will provide an output of 300V to potentially damage their devices and prevent theft. The system aims to reduce theft losses for power companies and stabilize supply voltages.
