  • Page 26: Evaluation Of Test Results

    5.7 Evaluation of Test Results Significance of Capacitance and Dissipation Factor and DC Resistivity A large percentage of electrical apparatus failures are due to a deteriorated condition of the insulation. Many of these failures can be anticipated by regular application of simple tests and with timely maintenance indicated by the tests.

  • Page 27: Other Test Methods

    Influence of Temperature Most insulation measurements have to be interpreted based on the temperature of the specimen. The dielectric losses of most insulation increase with temperature. In many cases, insulations have failed due to the cumulative effect of temperature, e.g. a rise in temperature causes a rise in dielectric loss which causes a further rise in temperature, etc.
