Topics
Possible new Approaches of Electrotechnical Diagnostics
Dissertation thesis should contain procedural and technological access of improving currently used methods of diagnostics. Furthermore thesis should discuss utilization of the newest diagnostics technologies. Goal of the thesis is in the searching for new criteria of insulation materials life time evaluation, for instance using measurement of partial discharges. Research should react e.g. on the new trends in the diagnostics appliances for partial discharges measurement. Study of the partial discharges in the higher and lower frequency ranges then today.
Interaction of Inhomogeneous Dielectric with Electric Field
The aim of doctoral thesis research should be associated with the phenomena that occur after insertion of an inhomogeneous dielectric into the outer electric field. Research connected with properties of selected dielectrics and their use for creating potential barriers in electrical appliances. In inhomogeneous dielectric the barrier causing rearrangements of electrical charge carriers and thus strong internal deformation of electric fields. Studying these phenomena can prevent negative consequences, which may lead to the destruction of a dielectric in so far not suspected places. The work should include a study of the interaction of multicomponent systems with the increased possibility of inhomogeneities at the interface with electric field, study of deformation of the electric field, process of space charge formation, description of the causes of phenomena and suggestions of its elimination.
Interaction of High-Voltage Electrical Insulation Systems with HVDC
The aim of the dissertation is to study applications of electrical insulation structures in new applications using high DC voltage. The work will revise and suggest diagnostic methods suitable for new applications, such as methodologies for measurement of partial discharges at DC voltage, the effect of long-term DC aging, slow polarization, space charge accumulation, the effect of various fillers, etc. The aim of the thesis should be search for new diagnostic methods and criteria in HVDC environment.
Development of New Electrical Insulating Liquids
The aim of this dissertation is developing of electrical insulating liquids of new generation. This fluid should not only meet the electrical requirements but also the requirements for environmental safety, sustainable development and economic requirements. In addition, these fluids must demonstrate higher fire safety while maintaining appropriate viscosity and pour point. An integral part of the work is the study of other important parameters such as oxidation stability, etc.
