PQube is a registered trademarkU.S. Trademark 78,587,957 of Power Standards Lab for an electronic measuring instrument that records power quality and electric energy on the electric power grid.
Applications PQube instruments are widely used to gather data for academic research, and at United States Department of Energy National LaboratoriesUsing Dashboards to Improve Energy and Comfort in Federal Buildings", K. Marini, Lawrence Berkeley National Lab, University of California eScholarship and state energy regulators."Verification of EnergyNet Methodology", California Energy Commission, December 2010 U.S. federal government agencies use PQubes to detect power quality issues – for example, the Federal Aviation Administration tracks disturbances at radar control centers."Programming and Operation of the PQube", Course by Federal Aviation Administration, June 2012
Each PQube instrument is traceable to the National Institute of Standards and Technology, so often these instruments are used in international academic and research environments."Monitorização em tempo-real de parâmetros de qualidade da rede elétrica a partir de diferentes locais em Portugal Continental", N. M. Salgado Campos, February 2012
PQubes are a key element in many smart grid projects,"Integrating GridAgents into SmartGrid Applications", D. Cohen et al., November 2010"Metering Plan", J.E. Pope, July 2012 recording power disturbance and power flow data to examine efficiency and reliability effects.
Information on the Web Approximately 50 PQubes, located in approximately 40 countries, have been designated by their owners as free public sources of information at http://map.pqube.com . The site is updated approximately every 2 minutes with worldwide power quality and energy recordings.
Data from these PQubes can be used, for example, for developing and testing power quality algorithms."Voltage Quality in Urban and Rural Areas", Timens et al., Netherlands, 9/2012"Fukushima, Mexico and Slovenia: Free Electric Power Recordings for Researchers" Available data include daily, weekly, and monthly files in GIF and Microsoft Excel CSV format. Voltage and current oscillographs are recorded during every power disturbance and these worldwide locations, and are freely available. Data from each worldwide site is updated approximately once per minute.
