This study presents the design and implementation of a low-cost SCADA system based on the ESP32 microcontroller, intended for teaching transient electrical phenomena in Industrial Electricity courses. The proposed solution enables real-time visualization of current waveforms during the startup of various electrical loads, including discharge lamps and three-phase motors. Current measurements were obtained using ACS712 sensors, processed by the ESP32, and displayed through a mobile-accessible web interface. Laboratory results showed strong agreement with theoretical values, with errors below 6.1% for resistive loads and under 12% for nonlinear loads. The system proved to be functional, accurate, and well-suited for educational use, providing a low-cost alternative to conventional measuring instruments. Its strengths, limitations, and opportunities for future improvement are also discussed.
