A development of a high-voltage high-resolution digital sampling wattmeter system for on-site/in-situ calibrations of metering systems for high-voltage power/energy measurements is described in the paper. The current input uses an optically isolated hybrid two-stage current transformer with electronic circuitry that performs A/D conversion. Data is transmitted to a ground station through a fiber optic...
The presentation focuses on trade metrology issues and opportunities in the energy sector, in particular the electrical energy sector in Canada arising from the worldwide deregulation of energy industries and the establishment of trading blocks and free trade zones. The need for a measurement assurance program for electric power and energy to address these issues and opportunities, and its economic...
An intercomparison of calibration systems for ac shunt up to audio frequencies between the National Research Council of Canada, Japan Electric Meters Inspection Corporation, and the National Institute of Standards and Technology, U.S.A., is presented. The transfer standard used for the intercomparison is a 10 A, 0.1 shunt
