    A definite deviation from the Eyring behavior (in fm/T ¿ 1/T) is found to occur with cable-insulating oils studied over the frequency range extending from 30 Hz to 100 MHz at temperatures between -80° and 27°C. The obtained activation parameters of dipole orientation in the oils exhibit a marked temperature dependence. The results indicate that changes occur in the dipole relaxation mechanism w...

    Knowing that oil is a weak link in a composite or impregnated dielectric system with reference to both dielectric strength and ease of contamination, many investigators have devoted great efforts to try to ascertain the best types of oil for various operating conditions. However, different investigators seem to have different opinions as to the best-suited type of oil for this purpose. It is the o... View full abstract»

    A comparison is made between several distribution functions of dielectric relaxation times, their corresponding frequency-dependent permittivities, and the resulting Argand diagrams. For each family of distributions, the shape of the Argand diagram changes only slowly with the parameters in the distribution. In most cases, rigorous procedures are necessary before a distribution function can be uni... View full abstract»

    Thermal aging studies were conducted on four encapsulated insulation systems on motorettes to establish their thermal rating. Encapsulation of Class-A and class-B insulation systems was found to upgrade a Class-A system from 105 to 138°C and a Class-B system from 130 to greater than 150°C. The effect of thermal shock on the thermal life is demonstrated to reduce the thermal life by a factor of 1... View full abstract»
