AbstractThe development of a reference system for on-site calibration of revenue metering systems in high voltage grids is described. The system consists of a three-phase power meter and high-accuracy current and voltage transformers (CTs and VTs). Measurements can be made up to 150 kV (system voltage) and line currents up to 5000 A. The initial characterization of the power meter and the CTs give excellent results, indicating that an overall system uncertainty of 200 μW/VA can be achieved.
