Abstract :
A mobile calibration system for in-situ calibration of voltage transformers is analysed with respect to measuring uncertainty under field conditions. The total basic uncertainty is better than /spl plusmn/0.015% respectively /spl plusmn/0.3 mrad. The system has been used to calibrate 570 capacitor voltage transformers.<>
