Sažetak
The measurement of fast pulsed-current and observation of time variations of the current are important for diagnostics of high-current discharges. The most convenient method of measurement is the application of the Rogowski coil which can measure variable currents in a very wide range of frequency and current. We introduce the Rogowski coil in the measurements of current of the ablative capillary discharge. The discharge current is a very important characteristic of the process and its determination allows the estimation of the period of the discharge cycle and of the total inductance of the circuit. In our experiments, the discharge currents were of the order of magnitude of several kA, the discharge cycle periods were of the order of 300 ns and the total inductances were of the order of a few tens of nH.
