摘要：
A comparison has been performed of the VSL and PTB reference setups for the calibration of industrial power transformer loss measurement systems (TLMS). Both setups are developed within the "ELPOW" European joint research project, with the aim to calibrate industrial TLMS as a complete system, rather than just via its individual components, with an overall uncertainty of better than 50 mu W/VA, for voltages up to 100 kV, currents up to 2 kA, and power factors down to zero. The initial comparison results show excellent agreement of the PTB and VSL reference setups, with typical differences less than 15 mu W/VA, well within the uncertainty of the setups.
