    The role of electrical insulation is critical for the proper operation of electrical equipment. Power equipment cannot operate without energy losses, which lead to rises in temperature. It is therefore essential to dissipate the heat generated by the energy losses, especially under high load conditions. Failing to do so results in premature aging, and ultimately to failure of the equipment. Heat d... View full abstract»

    The development of electrical insulation is closely associated with the development of electrical apparatus. Up to about 1925 only naturally occurring products such as asphalt, rubber, mica, cotton thread or fabric were generally used. Mineral oil-impregnated paper was used in transformers, capacitors, and underground cables at voltages up to 69 kV [1]. Then the first synthetic insulating material... View full abstract»

    Transmission and/or distribution systems are needed to transport electrical power from its generation site to the user locations. This paper reviews major DC power transmission technologies, concentrating on systems that are capable of long-distance transmission. Special attention is paid to lifetime models and the safe use of DC insulation systems. A relationship between the probability of failur... View full abstract»

    Maxwell and Felici developed the theoretical basis of geometrical stress control during the period 1846 to 1862. The first practical implementation, however, was that of Nagel in Germany in 1906 (Figure 1). He developed the socalled Nagel-bushing on the basis of conductive layers [1]. Around the same time, the Swiss professor Kuhlmann invented the refractive method [2]. His aim was to decrease the... View full abstract»

    Vegetable oil-based dielectrics have been available for the past 15 years; relevant articles have been published [1]-[3]. One practical advantage of using a vegetable-oil dielectric in a power transformer is its higher affinity to moisture, around 20 times higher than that of mineral oil at room temperature [4]. Power transformers containing vegetable oil are usually sealed, preventing water ingre... View full abstract»

    In this article the results of an experimental study comparing gas generation in the natural ester transformer liquid FR3 and in the mineral oil Gemini X, under PD and sparking faults, are presented. The total amounts of fault gases were reported in microliters rather than in parts per million. The results show that the key gases generated under PD faults and under sparking faults are hydrogen and... View full abstract»

    Condition monitoring and diagnosis (CMD) has proven effective in helping to ensure the safety of power grids. With development of the smart grid and ultra-high-voltage (UHV) transmission system, the demand for CMD systems has grown rapidly in China. In recent years many condition monitoring devices have been installed in the field, and much experience has been accumulated. At the same time, resear... View full abstract»
