FEM Modeling of Electric Field and Potential Distributions of MV XLPE Cables Containing Void Defect

M. Alsharif[1], P. Wallace[2], D. Hepburn[2], C. Zhou[2]
[1]Department of Physics, Faculty of Arts, Sebha University, Sebha, Libya
[2]School of Engineering & Computing, Glasgow Caledonian University, Glasgow, United Kingdom

Introduction: Failure in cable insulation is generally preceded by a degradation phase that may last several years. A significant cause of cable system failures is the breakdown of electrical insulation between the electrodes. The operational stresses that occur in cable insulation which ... En savoir plus

RFID-Enabled Temperature Sensor

I.M. Abdel-Motaleb[1], K. Allen [1]
[1]Department of Electrical Engineering, Northern Illinois University, DeKalb, IL, USA

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value ... En savoir plus

Finite Element Modeling of a Pulsed Eddy Current Probe for Steam Generator Tube Inspection

S. G. Mokros[1, 2], V. K. Babbar[1], T. W. Krause[1], J. Morelli[2]
[1]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada
[2]Department of Physics, Engineering Physics and Astronomy, Queen's University, Kingston, ON, Canada

Steam generator (SG) tubes in CANDU® nuclear reactors can lose efficiency in the presence of corrosion and its by-products. Condition monitoring of support structures could help direct maintenance activities and thereby increase SG tube lifetime. Pulsed eddy current (PEC) has been ... En savoir plus

[1]University of Houston, Houston, TX, USA

NASA is funding the development of a high-fidelity fully superconducting machine sizing tool able to generate optimized designs based on thrust requirements and design constraints. Several mechanical challenges need to be overcome during the design of the torque transfer components. ... En savoir plus

Heat Propagation Improvement in YBCO-Coated Conductors for Superconducting Fault Current Limiters

D. M. Djokic[1], L. Antognazza[1], M. Abplanalp[2], M. Decroux[1]
[1]DPMC, University of Geneva, Geneva, Switzerland
[2]ABB Corporate Research Centre, Dättwil, Switzerland

YBCO Coated Conductors (CCs), used for applications in Resistive Superconducting Fault Current Limiters (RSFCLs), are known to have insufficiently high Normal Zone Propagation Velocity (NZPV) during quench events. The improvement can be made by enhancing the thermal conductivity of YBCO ... En savoir plus

The Acoustoelastic Effect: EMAT Excitation and Reception of Lamb Waves in Pre-Stressed Metal Sheets

R.M.G. Ferrari[1]
[1]Danieli Automation S.p.A., Buttrio, UD, Italy

The acoustoelastic effect relates the change in the speed of an acoustic wave travelling in a solid, to the pre-stress of the propagation medium. In this work the possibility of assessing nondestructively the stress status in metal sheets, by using the acoustoelastic effect, is ... En savoir plus

Evaluation Of AC Loss And Temperature Distribution In High Temperature Superconducting Tape Using COMSOL Multiphysics

G. Konar, and N. Charaborty
Jadavpur University, Kolkata, West Bengal, India

High temperature superconductors (HTS) are promising candidates for electrical power applications. However, the superconductors exhibits energy loss known as AC loss when exposed to time varying external magnetic field and/or transport current. In this paper, AC loss in an elliptical Ag ...
