    The paper deals with the models for estimating the life of electrical insulation under multiple stress conditions. In a first approach, simple models, the inverse-power law and the exponential, are considered for electrical aging; they are combined with the Arrhenius model to find the life equation of insulating materials under temperature and voltage. This equation is discussed and the correspond... View full abstract»

    Results are presented on the weathering behavior of EPDM compounds suitable as a protective housing material for HV plastic insulators. Two accelerated tests have been used: thermal aging under pressurized O2, and Xenon lamp irradiation. Structural changes are followed through swelling and ATR infra-red speotroscopy measurements. The efficiency of various UV absorbers is compared with respect to s... View full abstract»

    The location of electrical breakdown in a composite insulating system has been measured. In these experiments, a paper sample was mounted so that it connected the two electrodes. Electrode structures ranging from plane-plane to sphere sphere were used. The electrode-paper system was tested in oil to determine the properties of an oil paper interface. The data indicated that, in a carefully prepare... View full abstract»

    This paper describes a power cable insulation with a tree growth inhibiting additive that is nowommer commercially available for use by the electric utilities. The new insulating resin inhibits the growth of both electrical and water trees. A major cause of insulation failure is the progressive ive degradation process called treeing. There is general agreement that electrical and water trees cause... View full abstract»

    This paper presents the results of 60 Hz, dc, and impulse voltage breakdown tests on miniature XLPE cables containing water trees. To produce the water trees, the cables were immersed in water and subjected to high voltage at a frequency of 1 kHz for periods up to 1000 h. The dc and impulse breakdown voltages of virgin cable were similar and about twice the peak value of the ac breakdown voltage. ... View full abstract»

    This paper presents an electrostatic study of free conducting particles that contaminate com pressed gas-insulated high voltage apparatus and transmission lines. Analytical and numerical techniques are used to describe the effect of the particle charge and the magnitude of the ambient electric field on the field intensification on and near the particle surface. The electrostatic force acting on fi... View full abstract»

    The impulse withstand of insulating liquids in divergent fields is presently being studied with particular atten tion in regards foreseeable changes in the nature of mineral oils, and in regards the behavior of equipment subjected to lightning impulses. A draft standard is presently under study by the IEC. Tests based on this draft standard were undertaken on ten traditional naphthenic oils, and o... View full abstract»

    The steady state condition of heat flow is important to design engineers to establish norms for insulation systems in respect to operating voltage and consequent temperature rise to prevent thermal instability, causing run-away conditions. The temperature distribution equation has been solved and the results have been applied to three practical situations, e. g. (1) ideally cooled system of electr... View full abstract»

    Several kinds of insulation systems, which were developed for high voltage coil insulation for motors and generators, are examined for insulation damage caused by mechanical stresses. Tests have been carried out on electrical properties under bending stress, i. e. the critical deformation characteristics which are defined as the maximum deformations able to withstand a fixed proof voltage, the fat...

    This paper presents the deformation and fracture behavior of stator windings subjected to bending loads. A series of bending tests were carried out on four kinds of stator windings, which were composed of steel solid bar or copper strands and mica-splitting tapes, and were impregnated with epoxy and polyester resins. The strain produced on the insulation surface and the deflection of the stator wi... View full abstract»
