[Analysis Case] Transient Eddy Current Analysis in Conductors Due to Pulsed Current
For the evaluation and visualization of pulsed eddy current testing (PEC)! High-precision simulation of transient eddy current changes after current off and behavior around defects.
Defect detection in aluminum conductors and similar materials (Pulsed Eddy Current Testing: PEC) requires a thorough understanding of the transient eddy current time variation immediately after the current is turned off and the flow around defects. This time, we will introduce a visualization case using the dynamic magnetic field analysis software "PHOTO-EDDY." In this analysis, we reproduce the behavior of eddy current concentration (skin effect) on the surface of the conductor immediately after the rectangular pulse current is turned off, showing how it reaches the defect depth and spreads into the deeper layers over time. The local changes in current density at the defect site can also be visually evaluated by setting the skin layer mesh. 【Features and Benefits of Introduction】 - Time-series visualization of eddy currents: Clearly evaluate transient diffusion behavior and local concentration. - High-precision modeling: Analyze minute defects with mesh division that considers the skin effect. - Optimization of non-destructive testing: Contribute to the preliminary examination and efficiency of testing conditions (pulse width, etc.). 【Overview of Analysis Case】 - Analysis target: Aluminum conductor (with through holes and defects) & excitation coil (compliant with TEAM Problem 27). - Evaluation items: Time-series transition of transient eddy current density distribution (1.0e-6 to 1.0e-3 [sec]). - Software used: Dynamic magnetic field analysis software PHOTO-EDDY. *For detailed data and results, please feel free to download the PDF or contact us.
