The global demand for electric power continues to increase in most countries but in particular in non-OECD (Organisation for Economic Cooperation and Development) countries [1]. Often the generation is located far from the consumers, and this require

A system for the measurement of surface potential on epoxy insulator within a direct-current (DC) gas-insulated system (GIS) of 320 kV nominal voltage is presented. Challenges encountered were the operating conditions: applied voltages up to 250 kV -

DC field measurements of the electric field around a cable termination have been performed. The field variation along the surface as well as its time development after voltage application is studied. The agreement between measured and simulated resul

Even under corona-free conditions, insulating structures (materials) may be charged in DC fields. This is due to the fact that air has a finite ionic conductivity. The finite conductivity of air results from charges generated by background radio acti

A method was established for demonstrating charge generation on the surfaces of dental materials by means of mechanical loading with different forces. With this experimental set-up charges could be extracted both from the surfaces that were mechanica

Knowledge of the external field distribution around high voltage apparatus is of vital importance. As a part of the effort to improve the physical understanding of the DC field distribution outside high voltage apparatus, a small probe that can measu
