    In this paper, a low-cost Power Systems Metrology Laboratory, based on the Raspberry Pi board and the ADE7878 energy metering IC is presented. The designed experimental platform is intended for developing skills among the undergraduate students of the University of Strathclyde, Glasgow, and the Autonomous University of Yucatan, Mexico. A series of exercises have been developed in order to measure different Power quantities and to evaluate different definitions of such quantities to observe how the accuracy of the measurements is affected, particularly, when non-sinusoidal conditions exist. The system is capable to perform measurements of single or three-phase, employing current transformers. A set of Simulink blocks is ready to use for the students, including PMU algorithms. The proposed laboratory facilitate the evaluation of new algorithms and functions, developed by the students.
