Abstract

This paper presents a real-time 3-phase power measurement instrument development using the ESP32 microcontroller and analog sensors. The instrument measures key electrical parameters including RMS voltage and current, real power, apparent power, reactive power and power factor for each phase of a 3-phase system. Key components used include the ZMPT101B voltage sensor, ACS712 current sensor, a 20x4 I2C LCD display and push buttons for manual data navigation. The system implements time-domain sampling and cross-correlation techniques for accurate phase angle and power factor calculations. The performance evaluation demonstrates its accuracy suitable for educational applications, as the measurement error compared to reference instruments was less than 2%.
