Establishment of 40,000 A Rogowski coil calibration system and its uncertainty analysis

System for calibrating Rogowski coil(RC) up to primary current of 40,000 A have been established by employing standard current transformer(CT), CT comparator and voltage to current converter(VCC). The expanded uncertainty is 0.021 % ~ 0.230 % for ratio error and 0.3 min ~ 1.9 min for phase displacem...

Zusammenfassung:System for calibrating Rogowski coil(RC) up to primary current of 40,000 A have been established by employing standard current transformer(CT), CT comparator and voltage to current converter(VCC). The expanded uncertainty is 0.021 % ~ 0.230 % for ratio error and 0.3 min ~ 1.9 min for phase displacement in the primary current ranges of 10 ~ 40,000 A.
