摘要：
A current sensor for the analysis of conducted Radio-Frequency Interference (RFI), based on an air-cored and screened Rogowski coil, is presented. The sensor is realised as a convenient current clamp, suitable for on-site measurements, e.g. in industrial environments. The probe is insensitive to strong mains power frequency currents, electric and magnetic fields, and parasitic air gap. With an incorporated wide-band amplifier a transimpedance characteristic of 0.5 muH in parallel with 5 Omega is realised. The effective frequency range is larger than 9 kHz - 30 MHz. It can be used both for time-domain measurements using oscilloscopes and as a probe (with a suitable antenna factor) for Electromagnetic Compatibility (EMC) spectrum analysers.
