Study on design of visual intelligent detection instrument for aviation cable fault

open access: yesXibei Gongye Daxue Xuebao, 2021
Aviation cable is used to transmit electric energy and signal, and its performance directly affects the safety of aircraft. It is difficult to locate cable faults on aircraft and there is a lack of suitable high-precision detection equipment.

Conductive Ink Printed Fabric Antenna with Aperture Feeding Technique

open access: yesApplied Sciences, 2023
Screen-printed and inkjet-printed conductive fabric antennas have been investigated in this manuscript. The former showed optimal radiation performance after fabrication and measurement, which was the basis for developing a new fabric antenna feeding ...

An equivalent circuit for the evaluation of cross-country fault currents in medium voltage (MV) distribution networks [PDF]

open access: yes, 2018
A Cross-Country Fault (CCF) is the simultaneous occurrence of a couple of Line-to-Ground Faults (LGFs), affecting different phases of same feeder or of two distinct ones, at different fault locations.

Spectral Index of the Diffuse Radio Background Measured From 100 to 200 MHz [PDF]

open access: yes, 2008
The mean absolute brightness temperature of the diffuse radio background was measured as a function of frequency in a continuous band between 100 and 200 MHz over an effective solid angle of ~pi str at high Galactic latitude.

Electric Field Determination in DC Polymeric Power Cable in the Presence of Space Charge [PDF]

open access: yes, 2007
The pulsed electroacoustic (PEA) technique was used to perform space charge measurements in polymeric power cables. However, for a practical dc power cable the electric field is affected by conductivity of the material, which is a function of both ...

Steady State Assessment of Shunt Compensated EHV Insulated Cables by Means of Multiconductor Cell Analysis (MCA)

open access: yesEnergies, 2012
The author has already presented some papers which allow studying cable systems by means of the multiconductor cell analysis (MCA). This method considers the cable system in its real asymmetry without simplified and approximated hypotheses.
