IoT enabled smart power quality analysis in three phase electrical systems with practical implementation.

This project shows how to build and use an Internet of Things (IoT) system that monitors power quality in real time on three‑phase electrical networks. Poor power quality shows up as voltage swings, current imbalances, and power‑factor errors, and these problems can hurt modern power grids and smart‑home systems. The proposed design uses a set of accurate voltage and current sensors connected to a fast microcontroller. The microcontroller continuously reads the three‑phase voltages and currents. It then turns the raw sensor data into key power‑quality numbers: active power, reactive power, apparent power, power factor, and frequency changes. A built‑in Wi‑Fi module sends the processed data to a cloud‑based IoT platform.

From the cloud you can watch the data remotely, store it for later analysis, and get alerts when something abnormal happens. The project also covers practical steps such as calibrating the sensors, conditioning the signals, and setting up secure cloud communication. It gives engineering students clear instructions to design, construct, and test a scalable power‑monitoring system, linking classroom theory with real‑world IoT automation.
