  1. 1. Study of different methodologies to determine relative dielectric constant of given substrate using fabrication, modelling and measurement strategies

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Anders Lundberg; [2021]
    Nyckelord :Relative dielectric constant; relative permittivity; PCB substrate material;

    Sammanfattning : In this thesis, different methods for measuring the relative dielectric constant is investigated using simulations and experimental approaches. The first method is known as the S-parameter inversion method. In this method formulae is used to calculate the characteristic impedance of the microstrip line from measured S-parameters. LÄS MER

  3. 2. Measurements of resistivity in transformer insulation liquids

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Jonathan Hägerbrand; [2020]
    Nyckelord :transformer oil; resistivity; ions; ion drift model; HVDC; contact resistance;

    Sammanfattning : This thesis focuses on measuring techniques and results of resistivity in four commercially available insulating transformer oils: mineral oil, ester oil and two isoparaffin oils. Two measuring techniques, the industrially used diagnostic system for electrical insulation IDA and the Labview implemented Triangular Method, are used for resistivity measurements and the techniques are compared, a correction algorithm to the triangular method is suggested.

    Sammanfattning : This thesis studies a sensing method for assessing the quality of liquid fluids used invehicles such as fuel, urea, break oil and coolant, etc. Dielectric constant is one of the important indicators of liquid fluids quality. LÄS MER

  5. 4. MEASUREMENT OF DIELECTRIC CONSTANT FOR WATER AND ITS TEMPERATURE DEPENDENCE AT 0 AND 86ºC

    Kandidat-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Sergio Apicella Fernández; [2014]
    Nyckelord :;

    Sammanfattning : The dielectric properties determine the electrical characteristics of materials. These properties are important for understanding the behavior of materials and how they can interact with each other. LÄS MER

  7. 5. Design of Singly Split Single Ring Resonator for Measurement of Dielectric Constant of Materials using Resonant Method

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Abdul-Nafiu Abiodun Jabita; [2013]
    Nyckelord :Ring Resonator; Split Ring Resonator; Measuring Dielectric Constant; Measuring Dielectric Constant using Resonant Method; Resonant Method;

    Sammanfattning : Scientists and engineers measure dielectric constant because it gives them better understanding of materials and helps them to know how to integrate these materials into their design processes;it also helps them to shorten design life cycle,and aside these two functions,it has numerous uses all of which cannot be enumerated in this section.Owing to its usefulness,various measurement methods of dielectric constant of materials have been developed over the years.
