    Keywords : GPR; the soil water content; electrical permittivity; parameter Q*;

    Abstract : Ground Penetrating Radar (GPR) is an effective tool to measure the geological properties. A lot of information can be interpreted from the GPR data, such as soil water content. READ MORE

  4. 13. Broadband Dieletric Properties of Impregnated Transformer Paper Insulation at Various Moisture Contents

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Jialu Cheng; [2011]
    Keywords : broadband dielectric spectroscopy; transformer paper; Karl Fischer titration;

    Abstract : The actual life of a transformer is determined by ageing of the cellulosic insulation such as transformer paper. The presence of moisture in the insulation system decreases the electrical strength of paper and accelerates the aging. READ MORE

  5. 14. Design of a Cylindrical Cavity Resonator for Measurements of Electrical Properties of Dielectric Materials

    University essay from Avdelningen för elektronik, matematik och naturvetenskap
