摘要
The applicability of Rogowski coils for high precision measurements of 50 Hz currents is studied. In the setup, Rogowski coils serve as current sensors and the amplitude and phase are determined with a sampling voltmeter. Another measurement channel enables current ratio and electrical power measurements. Preliminary expanded uncertainties are of the order of 30 ppm in current and 40 murad in phase.
