An Eddy Current Testing Platform System for Pipe Defect Inspection Based on an Optimized Eddy Current Technique Probe Design

The use of the eddy current technique (ECT) for the non-destructive testing of conducting materials has become increasingly important in the past few years. The use of the non-destructive ECT plays a key role in the ensuring the safety and integrity of the large industrial structures such as oil and gas pipelines. This paper introduce a novel ECT probe design integrated with the distributed ECT...

Transient 3-D Eddy Current Analysis in a Superconducting Magnet System Using an Integral Approach

The Wendelstein 7-X is a thermonuclear fusion experiment being built at the Greifswald Branch Institute of the Max-Planck-Institut für Plasmaphysik (IPP). The eddy current distribution is investigated during a transient process in the superconducting coils of the magnet system. Application of volume-grid methods (e.g. FEM) for calculations of the eddy currents in the magnet system is difficult ...

Eddy current

Eddy currents (also called Foucault currents[1]) are loops of electrical current induced within conductors by a changing magnetic field in the conductor, due to Faraday’s law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. They can be induced within nearby stationary conductors by a time-varying magnetic field created by anAC el...

Stress Measurement Using Pulsed Eddy Current Thermography

This paper reports a noncontact inspection method, using Pulsed Eddy Current (PEC) stimulated thermography, for the evaluation of the anisotropic dependency of electrical conductivity of steel exposed to tensile stress. This method combines microscope lens based thermography with PEC using a rectangular excitation coil, giving directional excitation, to infer the electromagnetic properties vari...
