    A review of the current state of understanding of dielectric mixture properties, and approaches to use numerical calculations for their modeling are presented. It is shown that interfacial polarization can yield different non-Debye dielectric responses depending on the properties of the constituents, their concentrations and geometrical arrangements. Future challenges on the subject are also discu... View full abstract»

    The author discusses some of the problems associated with data fitting, particularly the case of uncertainties in all the variables, the possibly misleading results of algorithmic convergence, and also the limitations imposed by some commercial software. He suggests that the presence of local minima in the fitting function means that the parameters derived from the fitting may be subject to much l... View full abstract»

    The influence of high electrical DC fields (>20 kV/mm) on aging, polarization and on the morphology of polyethylene (PE) is discussed. Infrared and positron annihilation spectroscopy measurements as well as capacitance measurements tend to suggest that the polymer morphology is modified by high fields. The author shows that the accelerated electrical aging characteristics of PE are linked directly... View full abstract»

    The Kerr electro-optic field mapping technique has been used to study space charge effects in HV pulsed propylene carbonate (C4H6O3) using stainless steel parallel-plane, aluminum blade-plane, and aluminum point-plane electrodes. Measurements presented here were taken using a circular polariscope with aligned polarizers at room temperature (T ∼ 20 to 27°C).... View full abstract»

    It is shown that the electrical breakdown mechanisms have a generic form that can exhibit deterministic chaos at sub-breakdown stresses, given a suitable parameter range. Calculation of temperature fluctuations in the thermal runaway mechanism is used to illustrate the behavior, and show the trends that may occur. Electrical tree propagation is used to outline the characteristics of deterministic ... View full abstract»

    Fifty years ago, the concept of an intrinsic electric strength for insulating solids was fashionable. It was supported by the sophisticated theoretical models of von Hippel, Frohlich and others for the interaction of electrons with crystal lattices in an electric field. The models came to be applied, rather implausibly perhaps, to polymers such as semi-crystalline polyethylene (PE). In that climat... View full abstract»

    The adoption of a field-theoretical approach to problems arising in the framework of electrical insulation is discussed with reference to six main topics, which have been addressed over the last 30 years. These include uniform field electrodes, Green's differential equation, electrode surface roughness, induced charge, electrostatic probes, and partial discharge transients, together with several f...

    Results are demonstrated that show that for a given time-domain measurement of a relaxational system to given accuracy, it is possible to compute the equivalent frequency-domain response to comparable accuracy. The computation is well defined, numerically stable, and is independent of any assumed functional form. The error propagation is given by explicit analytical results that allow for experime...

    Breakdown theories yield a specified time to breakdown for fields exceeding a critical value, whereas experiment shows that times-to-breakdown and breakdown fields are different on a sample-to-sample basis. This has forced the use of a statistical approach to failure, often without a clear physical understanding of the pertinent parameters. A general methodology that allows failure statistics to b...
