This paper presents the impact of temperature on electrical characteristics of a free-burning arc including voltage and power. By decreasing the arc current during the extinction, the arc temperature decreases as well. Beside, to change the arc tempe

The aim of this work is the investigation of layered dielectrics under DC voltage stress. For this purpose, two layered test samples were made, which contain one layer without fillers and the other made of the same silicone, mixed with a specific amo

The aim of this work is the investigation of the electrical properties of such layered dielectrics under high DC stress. The individual layers have different dielectric strengths, which are dependent on the electric conductivity and the temperature.

Under normal operating conditions hermetically sealed power transformers undergo load cycles resulting in pressure and temperature variation. With decreasing pressure, the dissolved gases diffuse out of the insulation liquid and accumulate in gas pha

This study presents investigations aiming at substituting conventional air or oil insulated enameled wires with water-filled ones for ac supplied applications. In this regard, twisted enameled pairs were prepared. Accordingly, ac breakdown voltage of

As the paper insulation in oil-filled power transformers is not easily accessible, a lot of attempts have been paid to indirectly estimate condition of the paper insulation through measurement of the diffused chemicals in the oil as aging indicators.
