Rogowski coils are widely used as high pulsed current sensors in resistance welding applications. The operating conditions of the coils determine the requirements for their calibration. A new calibration system has been developed at National Research Council (NRC) Canada for calibrating current sensing coils and weld current monitors (WCMs) used in AC resistance welding. The calibration system, which includes a high-current source and a coaxial copper cage, has been evaluated at peak pulsed… CONTINUE READING
