    Keysight N7040A Rogowski AC Current ProbeThe N7040A, N7041A and N7042A family of Rogowski AC current probes conveniently measure large AC current. These probes have a flexible clip-around sensor coil that can easily be wrapped around current carrying test points for measurement and can measure large current without increase in transducer size. These probes come with an AC power adapter and 4x batteries to power the probe, and they can be used with any oscilloscope with 1 MΩ BNC interface.

    How does a Rogowski current transducer work?

    Keysight Rogowski AC Current Probe
    1. The voltage induced in a Rogowski coil is proportional to the rate of change of current enclosed by the coil-loop
    2. The coil voltage is integrated to produce a voltage proportional to the current
    3. Because the Rogowski coil uses air core, it can measure large currents without saturation
    4. Rogowski coil is the best method to measure several kAs of AC current
