    A dipolar theory of thermally stimulated currents taking into account the thermal dependence of the equilibrium polarization has been tested in the glass transition range of a series of polymers selected for their well-resolved relaxation spectra and the absence of any significant bulk conductivity (triblock, diblock, and star-shaped styreneisoprene copolymers). Systematic studies of the effect ex... View full abstract»

    Previously, it has been found that absorption charge is associated with the accumulation of a fixed number of charges at the electrode. Also, under short-circuit, the accumulated charges are scarcely discharged, but a considerable part of them can be discharged by heating. In this paper, the current under a field with reversed polarity is described. A considerable part of the accumulated charges c... View full abstract»

    Electron injection into polymers from field stress concentration sites is now generally accepted as important for the initiation of electrical trees, although very few published studieshave so far provided direct evidence for this. By means of the thermally stimulated discharge (TSD) technique in low density polyethylene (LDPE) double needle samples, electronic space charge densities of 2.7×10-3 ... View full abstract»

    The electrical breakdown process in highly purified and degassed liquid hydrocarbons has been studied, using high speed schlieren photography as well as photomultipliers and an optical multichannel analyzer. It was shown that the breakdown process appears to be initiated primarily on the cathode surface. The ensuing formation of tree-like streamers was found to be associated with light emission. T...

    The shadowgraphic image reflects only those regions of disturbance occurring in a dielectric liquid, which differ in refractive index from their surroundings. The time required for the onset of a prebreakdown disturbance after the application of a step voltage, and the rate of growth of the disturbance depend strongly on the viscosity (or the temperature) of the liquid. The refractive index is low... View full abstract»

    This paper describes the effect of prestressing on the breakdown strength and time lag of lowdensity polyethylene films subjected to square pulses of 100 ns width. When prestress and impulse fields are opposite in polarity, the 50% breakdown strength Eb decreases from 4.9 to 3.4 MV/cm as the prestressing field is increased from 0 to 4.6 MV/cm. When prestress and impulse fields have the same polari... View full abstract»

    Organic materials to be used for the electrical insulation of superconducting magnet coilsin large fusion reactors must withstand electrical stresses under high mechanical loads, extreme temperatures, and intense nuclear radiation. In this paper, measurements at room temperature are reported on the effects of mechanical compressive and tensile stresses on the dielectric strengths of bi-stretched p... View full abstract»

    This paper describes the correlation between tracking phenomena and the behavior of dissolved and deposited metals from copper or brass electrodes at the interface between an electrolyte and paper phenolic laminate. The test method resembles the IEC tracking test, but with the application of a low dc voltage. The paper also describes the results of an analysis of the dissolved and deposited metals...

    The gaseous degradation products of low density polyethylene exposed to corona discharges were investigated. Temperature and applied voltage were varied independently in order to determine the effect of each on the chemical processes involved in the degradation. Based upon statistical analysis of the results, temperature was found to have an anomalous effect on the accumulation of organic gas prod... View full abstract»

  • Multi-Stress Endurance Tests on High-Voltage Motor Insulations, With Equal Acceleration Of Each Stress

    An ageing test was performed on two high-voltage motor insulation systems using three principal ageing stresses: temperature, electric field, and mechanical stress. An equal acceleration of each stress was used with the goal of an ageing process identical with that at service conditions. For the determination of the true acceleration factor a parallel ¿¿ageing¿¿ test at service conditions was run,... View full abstract»

    A general method for the solution of ac low frequency electric fields in insulating systems is proposed. The method is based on decoupling Maxwell's equations, and their solution can beimplemented analytically or numerically. The finite difference numerical method is easily implemented to solve the field in polluted insulators. View full abstract»

    The electric field configuration has been analyzed numerically by the charge simulation method near a contact point where two media having surface or volume conductivity meet an electrode. Surface conduction with uniform surface resistivity moderates the field singularity, resulting in a uniform field throughout both media for very low resistivity. On the other hand, volume conduction magnifies th... View full abstract»

    Dielectric loss of the PP/oil system was decreased by high voltage application beofe the dielectric measurement. The extent of decrease depends on the magnitude and the duration of the prestress voltage. This decrease in dielectric loss is caused by trapping of the impurities on the interface of the PP/oil. We found that the dielectric loss tends to go back up to the initial value with time after ... View full abstract»

    The dissipation factor, sensitive to voltage stress, is invariably used for quality assessment of high voltage rotating machine insulation. When it is subjected to higher electrical stresses, insulation hysteresis occurs during these measurements, which is similar to those exhibited by ferromagnetic materials. The influence of the insulation hysteresis coefficient for micaceous composites used in ... View full abstract»
