N2 - Abstract - Non-intrusive measurement methods allow for the timely detection of system impedance changes through in-situ detection without disassembling the components of the system under test. This enables the isolation of potential faulty components and facilitates condition-based maintenance. By constructing an equivalent circuit model of the current probe and analyzing its frequency response curve based on the formula, the impact of distributed parameters on the current probe is studied. Electromagnetic simulation software is employed to build an electromagnetic model of the current probe, optimizing parameters such as the number of coil turns, core material, and core characteristics. Finally, a small-size broadband current probe and a corresponding calibration fixture are designed. Experimental results demonstrate that the current probe meets the design requirements and is suitable for broadband impedance measurements.
