Calibration system for electronic instrument transformers

A high-accuracy system for calibration of electronic instrument transformers with digital output is described. Its design is based on International Electrotechnical Commission (IEC) standards 61850, 60044-8, and 60044-7. The performance of the calibration system has been evaluated. Its estimated relative uncertainty (2σ) is within 40·10-6 in magnitude and within 40 μrad in phase.
