Rogowski Flexible Coil AC Currrent Probe MH-RC03 series
1. The coil output gives a low voltage signal, therefore there is no danger from open-circuited secondary.
This makes Rogowski transducers extremely suitable for temporary measurements, for example in combination with portable analysers.
2. Unlike traditional current transformer with magnetic core, the Rogowski coil is a non-intrusive transducer. Since it has no hard core,
it draws no power from the main circuit carrying the current to be measured.
3. The absence of magnetic core grants a wide frequency response.
1. Three phases with three ranges by switch
2. Rogowski coil with integrator
3. Current range can be customized
4. Accuracy: +/-1%
5. Harmonic measurement up to 51 times
