    Chemical mechanisms of tracking and erosion are reviewed by considering mechanisms of conduction and molecular structure of polymers. It is shown that track formation need not necessarily be by graphite formation and that degradation mechanisms cannot always be predicted by inspection of molecular steriochemistry.

    A new tracking test has been designed which substantially eliminates the faults of the standardized tracking tests. It has been used successfully over the past three years in the evaluation of the tracking resistance of cable insulations. Utilizing a liquid contaminant of ammonium chloride, tracking resistance measurements can be molded panels or on cable sections in a very short time with excelle... View full abstract»

    The interaction of varnish with magnet wire enamel can lead to a reduction in the thermal life rating of the insulation system (ASTM D2307-64T). The recognition of this reduction in life rating is encountered first by varnished twisted pairs of enameled wire. An attempt is made to determine the mechanism of this interaction by studying the system microscopically, by differential thermal analysis a... View full abstract»

    Thermal endurance tests to AIEE Standard 57 [1] have been performed in six laboratories each using self-prepared varnished specimens made from a common sample of polyester enameled wire and polyester varnish. The results have been analyzed to test the hypothesis of the departure from linearity of the relationship between the logarithm of life and the inverse of the absolute temperature. A comparis...

    Attempts to understand the mechanism of dielectric loss, based on laboratory testing of petroleum-derived transformer and cable oils, have led to several important conclusions. First, soluble copper at the parts per billion level has a large adverse effect on oil stability. Second, certain compound types tend to solubilize copper and thus lead to rapid oil degradation. Third, aromatic hydrocarbons... View full abstract»

    A study has been made of discharges occurring in voids. A sample of convenient size is described. A method of mea suring the discharge pulse has been developed which reduces the inductance of the circuit to a minimum. As a result it has been found that the pulses have rise times of the order of 1 ns which is shorter than previously anticipated. Extremely fast discharges may be counted. A method of...

  • The Armette Test for Evaluating Universal Motor Insulation Systems

    The "armette test" was devised to improve the quality of test data and reduce the cost of obtaining it. Test methods to date require the manufacture of an entire motor. Present data can be unduly influenced or even voided should the field change or failure occur during the test. The "armette" is a unit that consists of a simple shaft, laminations, magnet wire, insulation, and varnish. It differs f... View full abstract»
