21. Electrical Charges on Polymeric Insulator Surfaces and their Impact on Flashover Performance
Abstract : Utilization of remotely located sustainable energy resources such as solar, wind and hydro calls for further developments of long-distance electric power transmissions operating at ultra-high voltage (UHV) levels which may exceed 1000 kV ac and 800 kV dc utilized today. It is foreseen that insulation of such transmission systems is to be based on polymeric materials that can provide a number of technical benefits over traditionally used glass and porcelain based insulation.

23. Pre-breakdown Phenomena in Mineral Oil Based Nanofluids
Abstract : Mineral oil is a dielectric liquid commonly used in high voltage equipment such as power transformers. Interestingly, it has been experimentally observed that the dielectric strength of the mineral oil is improved when nanoparticles are added. READ MORE

25. Numerical modeling of pulsed volume discharges for the generation of ozone
Abstract : The pulsed electric volume discharge is a new alternativefor the efficient generation of ozone in compact systems. Thisthesis presents a parameter study of the reactions in this kindof homogeneous discharge, using a here developed numericalmodel DISCHEM which solves plasma chemical kinetic rate andenergy equations.
