Development of Rogowski Coil System for MFCG Pulse Current Measurement
As a kind of compact Pulsed Power Supply, Magnetic Flux Compression Generator (MFCG) can be used in many military fields. To measure the output current of a piston-type MFCG prototype, a Rogowski coil measurement system was developed. The principle of Rogowski coil measurement system was introduced firstly. Considering the MFCG current can continue for 3 ×10-4s~3 ×10-3s, with fluctuation amplitude of 102A~106A, so we choose the Rogowski coil working in the near-open mode. The relative electric parameters of the Rogowski coil as following: the self-induced coefficient 9.75mH, the mutual inductance 3.7 μH, the internal resistance 41.8 Ω. After the Rogowski coil system was manufactured, a standard LRC fluctuation current measurement experiment was accomplished to test and calibrate. The result showed that the veracity of the Rogowski coil system was high, more than 96％. During the piston-type MFCG principle experiment, the amplified current recorded by means of the Rogowski coil measurement system was 3 folds of the seed current, which is the first time to detect the amplified current in the piston-type MFCG fields.
