AbstractThe 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. A high-accuracy system for calibrating Rogowski coils at continuous AC currents was previously developed at NRC. However, in AC resistance welding, high pulsed currents are used. A new calibration system was developed to calibrate current sensors and related equipment under high pulsed currents.
