With increasing electrification of vehicles, integration of wind power, and novel power generation, new electrical stress formats are becoming more present and the ability to measure associated events is becoming ever-more demanding. Based on the assessment of industrial and scientific specifications, a ’dynamic current’ can be defined as a current waveform having transient (high-frequency) characteristics in the 80 ⋯ 200 kA, 0.5 ⋯ 1.5 MHz range, and steady-state (lowfrequency) components in the 0.2 ⋯ 2 kA, DC ⋯ 1 kHz range. In addition to reproducing such test waveforms in a controlled laboratory environment, observing the full spectrum of these waveforms imposes considerable challenges for measurement systems which are presented in this paper.
