Abstract	The design and development of an educational Star-Delta Starter Trainer Kit with a real-time inrush current monitoring system is presented in this paper. Giving electrical engineering students practical experience in comprehending the working principles and transient behaviour of three-phase induction motors is the project's main goal. A 16x2 I2C LCD display, a current transformer (CT) sensor, and an ESP8266 microcontroller are all included in the trainer kit. The peak inrush current, a brief but notable spike in current that happens when switching from the star to delta configuration, is recorded and shown by the system during motor startup. The ESP8266 processes the recorded data and displays it in real time, enabling users to see the inrush phenomenon without the need for an oscilloscope. The trainer kit also incorporates industrial safety features like single-phase and overcurrent protection. By bridging theoretical ideas with real-world application, the setup improves student learning through experimentation and observation.
