AbstractA reference system for on-site calibration and validation of revenue metering systems is realized. 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 power meter, the CTs, and the VTs were all calibrated. Based on the excellent results of the calibration of these components it is possible to predict the full system performance with an uncertainty of less than 100 μW/VA. This estimation was verified with a full system validation, showing that the system is much more accurate than required and that detrimental effects to the accuracy are well understood.
