Noninductive current probe

Hybrid Model for Bulk Current Injection Probe

A new hybrid-model for BCI probe is derived . This model is built based on the probe's internal structure without refinements, and by carrying out just one electrical measurement for the reflection coefficient, so that it can be generalized and used in studying the effect of layout parameters in the aim of improving the probe high frequency performance, which helps the developer in design stage...

Understanding Langmuir probe current-voltage characteristics

I give several simple examples of model Langmuir probe current-voltage I-V characteristics that help students learn how to interpret real I-V characteristics obtained in a plasma. Students can also create their own Langmuir probe I-V characteristics using a program with the plasma density, plasma potential, electron temperature, ion temperature, and probe area as input parameters. Some examples...

Standard Flaws for Eddy Current Probe

Calibration procedures for eddy current inspections often involve the use of artifact standards containing manufactured flaws. The manufactured flaw is assumed to be a good approximation of the type of flaw being sought during the inspection. These manufactured flaws are most often produced by electrical dis charge machining (EDM) , milling, or the controlled growth of fatigue cracks. With simp...

Nanosecond - Current Probe for High Voltage Experiments

A current probe has been designed which allows measurement of ns;pulsed currents in high voltage environments. The probe consists of a current transformer and an optical transducer. The transformer coil in a metallic torus is considered as a slow-wave transmission line and is terminated with its wave impedance. In this mode of operation current pulses shorter than twice the transit time of the ...
