    Using shadowgraphic techniques in conjunction with an Imacon camera, measurements of streamer velocities and minimum voltage required for streamer propagation (MVP) have been made with and without dc superimposed on voltage steps (1.2 μs rise time). This has been done in point-plane geometries and semi-uniform fields in a transformer oil alone as well as with pressboard barriers. Velocitie... View full abstract»

    The insulation strength of a vacuum gap bridged by a solid insulator is lower than that in the absence of the solid insulator. The triple junction formed by the solid insulator, electrode, and vacuum in vacuum devices (or a gas in high-pressure apparatus) has a critical influence on the withstand voltage level of the insulating gap. The electric field is calculated using the charge simulation tech... View full abstract»

    This paper first confirms that moisture absorption of XLPE (crosslinked polyethylene) obeys Fick's law. The effects of moisture absorption and temperature on water treeing in XLPE are then discussed. The results of physical and chemical tests of the sites of water trees are presented. Infrared Fourier Transform Spectro-scopy (FT-IR) test results show the chemical aspects of the deterioration. Fina... View full abstract»

    The amount of water in water trees has been measured as a function of tree length. It is roughly proportional to the volume of the water tree and the fraction of the tree volume filled with water is of the order of several percent. This water content in water trees is approximately proportional to the applied electric stress. View full abstract»

  • Etching and the Morphology of Cross-Linked Polyethylene Cable Insulation

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (7879 KB)

    The techniques of etching by carbon tetrachloride vapor and by permanganic acid are shown to be prone to artifacts, and so earlier conclusions based on these techniques, i.e. that XLPE cable insulation has a large scale (>> 10 µm) spherulitic texture structure, need to be reexamined. A comparison with XLPE film samples, where spherulite size is readily determinable by small-angle light sca... View full abstract»

  • Comparison of Single and Double Needle Tests for Evaluation of Resistance to Treeing Breakdown

    Publication Year: 1983, Page(s):42 - 47

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1826 KB)

    This paper describes results on treeing breakdown in organic insulating materials using diverging fields formed by two different types of electrode geometries. These were needle/plane (SNT) and needle/needle (DNT) systems. Characteristic voltage, voltage life, and short-time breakdown tests were performed so that a comparison between SNT and DNT could be made. Low-density polyethylene (LDPE), cros...

  • Dielectric Breakdown of Polyparabanic Acid (PPA) Film under Square Pulse Conditi ONS

    Publication Year: 1983, Page(s):48 - 52
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (520 KB)

    The dielectric breakdown characteristics of polyparabanic acid (PPA) film were investigated in a temperature range from 20 to 300°C, under square pulse conditions. The temperature dependence of the breakdown strength shows two distinct regions, referr-ed to as I (20-150°C) and II (150-300°C). In region I, the breakdown appears to be due to an electron avalanche mechanism. In region II, impulse ... View full abstract»

    The paper describes a method for estimating the life of high-voltage coil insulation under multiple stress conditions. Thermal and electrical stresses are considered. The final aim is to predict the life of insulation under normal voltage at normal temperature. The lifetime of the insulation is defined as the time until the residual ac short-time breakdown voltage decreases to the withstand test v... View full abstract»

    This paper presents a proposal for insulation diagnosis of 3 kV induction motor stator windings of mica splittings and solvent-type thermosetting resin insulation. Nondestructive and destructive tests were conducted on 29 windings it operation for 15 years or more. The average breakdown voltage (BDV), Vave of the coils was estimated using 10 to 12 coils from each winding. The relationship between ... View full abstract»

    The visualization of the deformation and division of a flat cylindrical gaseous cavity trapped in various dielectric liquids, subjected to ac fields (at different frequencies) has been made. A great variety of phenomena never previously mentioned is described and interpreted: the dielectrophoretic force (in absence of partial discharges in the gas) produces elongation and branching of the bubble w...

    The radiation resistance of ethylene-propylene-ethylidene norbornene terpolymer (EPDM) cured by peroxide was studied. Some properties of EPDM showed maxima with irradiation. The gel fraction dropped rapidly following the maximum, at a rate which increased with decreasing dose rate. The dose rate affects the rate of deterioration of mechanical properties; the lower the dose rate, the more the deter... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (391 KB)

    In insulation diagnosis it is essential to know the correlation between some nondestructive measurements and the residual breakdown voltage. All the nondestructive measurements should be translated to the assumed residual breakdown voltages with the aid of correlation curves. This paper discusses a simple method to derive the correlation curves. Model coils of epoxy-mica splittings insulation were... View full abstract»

    The effect of electrode polarity, material, and gap length on the direct breakdown voltage of degassed and oxygen-saturated silicone oil was determined using a point-sphere electrode configuration. The results are compared with those obtained for liquid paraffin under similar test conditions. The shape of the breakdown voltage versus gap length characteristics for both polarities of the point show... View full abstract»

    The field distribution of a "uniform field" electrode system which is usually employed in studying the particle initiated breakdown in SF6 and other compressed gases is analyzed by using the charge simulation method. The results indicate that field distribution of such a system is non-uniform under certain conditions and needs careful evaluation. View full abstract»
