Abstract : The design and implementation of an automatic multiphase intelligent switching system for a three-phase power supply are the subjects of this study. It offers a way to automatically switch between phases in the event of a power outage in the current phase. The system can be remotely monitored via a Bluetooth interface that connects to a mobile application that functions as a display panel. It also automatically detects the restoration of any or all of the mains' three phases and compares voltages against under voltage and overvoltage before changing over. Microcontrollers, HC05, transformers, transistors, and relay switches were used to do it.

Keywords : Microcontroller, Bluetooth, Mobile App, Multiphase, and Changeover Switch.
