| Abstract | Rogowski coils are widely used as high pulsed current sensors in resistance welding. Their operating conditions reflect on requirements for their calibration. A new calibration system has been developed at NRC Canada for calibrating current sensing coils and weld current monitors for AC resistance welding. The calibration system, which includes a high current source and a coaxial copper cage, has been evaluated at peak pulsed currents of up to 80 kA, at 60 Hz. The best expanded measurement uncertainties (k=2) have been estimated to be within 250 μA/A for magnitude and 175 μrad for phase. |
