Epoxy resin sheets were surface fluorinated in a laboratory vessel using a F2/N2 mixture with 12.5% F2 by volume at the different temperatures of 25, 55, 75, and 95 °C for the same time of 30 min, to investigate the effect of fluorination temperature on surface electrical properties. ATR-IR analyses indicate that fluorination led to substantial changes in surface chemical composition and structure,...
The present paper is devoted to the study of the Electrostatic Charging Tendency (ECT) of fresh (unused) and aged transformer oils using a spinning disk system. A series of experiments were conducted under laboratory controlled conditions. The monitored parameters (conductivity, dissipation factor, water content, dissolved decay products, resistivity, turbidity ...) show that the electrification currents...
