Abstract:

The breakdown of epoxide compounds at frequencies of above 1 kcps proves to be a heat effect even at room temperatures. Frequency can be used for speeded-up tests of epoxide compounds for service life at voltages less than the voltage of heat breakdown under the conditions of the tests. For a layer of the compound of a thickness of 3 mm in a non-uniform field long maintained voltage at a frequency of 50 cps amounts to not less than 12.5 kv with a probability of breakdown of 50. Taking into account the scattering of the specimens over periods of service the long maintained voltage with a probability of breakdown of 2 equals 9.5 kv. Author
