This article presents the design and implementation of an Arduino-based laboratory Phasor Measurement Unit (PMU) for power system analysis. The PMU is a crucial device used in power systems to measure and monitor phasors, frequencies, and voltages at various locations. The proposed laboratory PMU offers a cost-effective and accessible solution for educational and research purposes. The article describes the design methodology, hardware components, and software implementation of the Arduino-based PMU. Experimental results demonstrate the accuracy and reliability of the developed PMU, making it a valuable tool for power system analysis and education.
