Calibration of Rogowski Coils at High Pulsed Currents
Calibration of Rogowski Coils at High Pulsed Currents. The many applications of Rogowski coils include their use as current sensors in AC resistance welding. Weld quality depends on monitoring/controlling the welding currents. The accuracy of these current sensors matters, and so does the accuracy of their calibration.
