Paper Title
Design and Development of RFID-Based Security System for Lineman, Fault and Overload Detection in Distribution Line

Abstract
Electricity is an essential part of modern life, powering our homes, industries, and devices, with linemen playing a critical role in maintaining and ensuring proper functioning. A crucial component of this system is the relay, which acts as a safety device to prevent damage from electrical overloads or short circuits. Despite being available for a long time, relays have not been widely introduced to the distribution sector, resulting in manual operations that can be challenging to monitor during fault detection. Linemen face increasing risks during electrical line repairs, partly due to communication challenges between maintenance staff and linemen. Every year, there are many cases reported of overloading due to thefts. Electricity theft poses the risk of transformer overload, potentially resulting in the burning of transformer windings. Moreover, when theft is committed through methods such as hooking, it increases the likelihood of fatalities. Additionally, both overload and theft contribute to significant financial losses and interruptions in the distribution sector. To overcome these problems, the aim is to design a compact model where fault detection in the 3-phase system is done by a relay, and the signal is sent to the ESP 8266 using the NO-NC method. Through the Wi-Fi Module (ESP 8266) the message is then sent to the lineman’s phone. The apparatus employs a current sensor that is built into the item to identify situations of overload, which are indicated by a rise in current consumption. The sensor sends information to an Arduino Nano when it notices a change in consumption. The Arduino Nano then uses an ESP 8266 Wi-Fi module to send a notification message to the lineman’s smartphone. Lineman protection is provided by the use of RFID-RC522-based circuit breaker operations. To protect, linemen must be equipped with RFID tags. Because the circuit breaker has RFID readers installed, it can identify linemen and avoid inadvertent activation when performing repairs. By guaranteeing that only authorized individuals can operate the circuit breakers, this technology improves safety by lowering the possibility of mishaps.
