Description
The Rogowski probes of the RCP-XS series measure alternating current up to 12,000 Apk with a bandwidth of 2 Hz to 30 MHz, an accuracy of 1 % and a noise level of less than 2 to 18 mVpp. Within the measuring range, the output signal of the system and the current signal to be measured are always linear, so that the accuracy does not change with the current; the coil contains no magnetic saturation components and no magnetic core or saturation phenomena, no heating problem; the Rogowski coil contains no ferromagnetic materials and therefore has no hysteresis effect; the phase difference between the output signal and the current waveform is extremely small and can be less than 0.8°. The RCP-XS models are compact and easy to handle, they have a standard BNC interface and a 12 V DC connection. They can measure current signals with complex waveforms, such as transient inrush currents from power devices, sinusoidal currents of three-phase power supply systems, harmonic components of measured currents, current measurements of IGBTs and MOSFETs, etc.
