3. Development and application of high voltage dielectric spectroscopy for diagnosis of medium voltage XLPE cables
Sammanfattning : When polymer power cables were introduced into mediumvoltage applications in the late 1960s, the degradationphenomenon later referred to aswater treeingwas still unknown. However, this changedwithin a relatively short space of time. LÄS MER
4. Molecular Arrangement, Electronic Structure and Transport Properties in Surfactant Gel- and Related Systems Studied by Soft X-ray and Dielectric Spectroscopy
Sammanfattning : This thesis concerns studies of aqueous soft matter systems, especially surfactant micelle systems.The aim has been to study the molecular arrangement and electronic structure of the constituents of, as well as transport properties in such a system. LÄS MER
5. Partial Discharges Studied with Variable Frequency of the Applied Voltage
Sammanfattning : This thesis concerns partial discharge (PD) diagnostics withvariable frequency of applied voltage in the frequency range 1mHz - 400 Hz. The exploration of a new type of spectroscopythat combines partial discharge analysis and dielectricresponse is demonstrated. LÄS MER
