Course detail
FEKT-MPC-NDDAcad. year: 2023/2024
The course focuses on two areas of modern diagnostic materials, i.e. dielectric spectroscopy and acoustic and electromagnetic emission.Emphasis is put on the understanding of the issues, applying relevant knowledge and practical experience with diagnostic materials.The following topics are demonstrated during a semester:physical laws accompanying the behavior of dielectrics and insulators in electric field polarization happening in dielectrics, the behavior of materials in the DC and AC electric field, the fundamental aspects of conductivity, dielectric absorption, dielectric loss and dielectric strength materials. Furthermore, the basic types of electrical insulating materials due to their being sorted resistance degradation factors, in particular the temperature and electrical stress.In the area of acoustic and electric emissions will be:The emergence and spread of acoustic signals and electromagnetic emissions, types of diagnostic sensors, types of defects in composite systems, analysis of noise spectra using low-noise amplifiers, suitable measurement techniques and shielding systems.Students will enhance skills in diagnostics of materials, analysis of dielectric spectra analysis of noise spectra, programming in Matlab and communication over the GPIB and RS 232
