Real Time Transformer Fault Detection and Wireless Electrical Billing System Using Embedded System and IoT

Abstract

This project focuses on developing a real-time transformer monitoring and wireless electricity billing system using an embedded system combined with Internet of Things (IoT) technology. The system continuously observes important electrical parameters in power distribution networks to improve safety, control, and billing accuracy. Current Transformer (CT) and Potential Transformer (PT) sensors are used to sense current and voltage values, while a temperature sensor checks the heat level of the transformer. An Arduino microcontroller collects and processes this data, and the measured values are shown on an LCD for easy local monitoring. In summary, this system integrates fault detection, protection, and smart energy billing into a single IoT-based embedded solution. It improves transformer safety, simplifies maintenance, and ensures transparent energy usage monitoring, making it suitable for modern power distribution systems.
