The central finding of this investigation is that there is a power-law relationship between the local electric field concentration and the rate of defect-tip initiated conducting crack growth. By applying such a power-law conducting crack growth rate expression to the evaluation of the life of solid dielectrics, the empirical classical ageing law of insulation materials can be derived theoretically as a lobical result. All the results are universal and agree with the experimental data of oxide films.展开更多

The focus is on the investigation of some empirical facts in the Slovenian electricity market for households focusing on market segmentation, market concentration measures, real electricity price developments, and their implications for electrical energy consumption and consumer welfare. The authors apply descriptive statistics, Lorenz curve and Gini coefficient of concentration, and demand function using regression framework on time-series data. The authors found that the market liberalization and entry of new competitors have slightly caused variations in the patterns in real electricity price developments. Households＇ real income and real electricity prices for households are found as the crucial determinants for the electrical energy demands by households.展开更多
