PROTOTYPE OF LORA-BASED ELECTRICITY THEFT DETECTION DEVICE USING SUM OF ABSOLUTE DIFFERENCE (SAD) METHOD

Abstract

Electricity theft is a significant issue globally, including in Indonesia. It can happen in various locations such as residential areas, offices, industrial sites, and more. Electricity theft can severely impact the owners of electrical installations, leading to considerable financial losses. A device designed to monitor electricity usage and detect potential theft by comparing customer consumption data against distribution substation data could mitigate this issue. The device is installed on the customer’s meter, with real-time monitoring accessible via the web. The data is visualized in graphs, allowing easy detection of irregular consumption patterns. This research utilizes a PZEM 004-T current voltage sensor and an Arduino Uno microcontroller paired with a LoRa module for long-range communication. Additionally, the system is equipped with an ESP8266 microcontroller as a Wi-Fi module for web data display.
