PQube
From Wikipedia, the free encyclopedia

PQube is a registered trademark[1] of Power Standards Lab for an electronic measuring instrument that records power quality and electric energy on the electric power grid.
PQube instruments are widely used to gather data for academic research,[2][3][4] and at United States Department of Energy National Laboratories[5] and state energy regulators.[6] U.S. federal government agencies use PQubes to detect power quality issues – for example, the Federal Aviation Administration tracks disturbances at radar control centers.[7]
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.[8][2]
PQubes are a key element in many smart grid projects,[9][10] recording power disturbance and power flow data to examine efficiency and reliability effects.
