High-Frequency Behavior of Residual Current Devices

Residual current devices in LV

«Cahiers Techniques» is a collection of documents intended for engineers and technicians, people in the industry who are looking for more in-depth information in order to complement that given in product catalogues. Furthermore, these «Cahiers Techniques» are often considered as helpful «tools» for training courses. They provide knowledge on new technical and technological developments in the e...

Carbon Nanotube High Frequency Devices

Global Modeling of High-Frequency Devices

In this work, we utilize the Finite-Difference Time Domain (FDTD) Method coupled to a full band, Cellular Monte Carlo simulator to model high-frequency devices. Replacing the traditional Poisson solver with a more robust electromagnetic (EM) solver provides a complete solution of the Lorentz force resulting in a more accurate model for determining the small-signal response of microwave transist...

High-frequency eddy current conductivity spectroscopy for residual stress profiling in surface-treated nickel-base superalloys

Recent research results indicated that eddy current conductivity measurements can be exploited for nondestructive evaluation of subsurface residual stresses in surface-treated nickel-base superalloy components. Most of the previous experimental studies were conducted on highly peened (Almen 10-16A) specimens that exhibited harmful cold work in excess of 30% plastic strain. Such high level of co...

High Frequency Eddy Current Testing

This paper presents a nondestructive, high frequency electromagnetic evaluation method which can be applied for the examination of periodic conductive strips or conductive fibers using the evanescent modes generated in slits or in dielectric insulation between conductive fibers. For the detection of evanescent waves we propose the use of lenses with metamaterials, both conical Swiss roll type a...
