Pearson Wide-Band Current Probes measure surge and in-rush currents for EMC and other industries. A typical requirement is an 8x20, or 10x350, microsecond single shot pulse with current amplitudes greater than a kilo amp. The typical Pearson wide-band current probe will have a 0.01 V/A transfer impedance, or less, for this application. Pearson Electronics enjoys close relationships with most of the surge testing equipment manufactures and provides wide band current probes for use with their equipment.
