摘要：
High-voltage power metering systems based on electronic instrument transformers (EITs) have some advantages compared to the conventional ones. This paper describes an unique calibration method and device for the power metering system. High accuracy with the calibration method can be achieved. The estimated relative uncertainty of the device is about 200x10(-6) in magnitude and less than 110 mu rad in phase.
