Abstract :
A high accuracy system for calibration of electronic instrument transformers with digital output is described. Its design is based on IEC standards 61850, 60044-8, 60044-7. The calibration system has been built and its performance evaluated. Its estimated amplitude uncertainty is within 50middot10-6 and its estimated phase uncertainty within 50 murad
