Dielectric strength of transformer insulation

Electrical Engineering, 1937
This paper presents a summary of the results of over 2,000 tests on the dielectric strength of transformer oil and insulating material for impulse, switching, and 60-cycle voltages. From these tests the voltage-time characteristics of the 2 insulations tested may be established over the entire range from a fraction of a microsecond to more than one ...

DIELECTRICS ELECTRICAL STRENGTH

Yessenov Science Journal, 2023
Abstract. In human life, even in practice, solids play an important role. Metals, dielectrics, electrical engineering, semiconductors, electrons, magnets, conductors lying close to each other are all solids. It can be argued that the basis for the foundation of scientific and technological progress is a solid body.

Effects of dishomogeneities on the dielectric strength of real dielectrics

[1992] Proceedings of the 4th International Conference on Conduction and Breakdown in Solid Dielectrics, 2003
The local field set up by the inhomogeneities present in the dielectric matrix of power cable insulation is examined. A pure polymeric matrix is considered in AC regime, and the real local field set up by the presence of fillers or impurities is calculated by using a suitable mathematical model. On the hypothesis that the AC breakdown stress is closely

Dielectric strength of mineral oils

Electrical Engineering, 1935
The correlation of the pressure and temperature effects in determining the dielectric strength of mineral insulating oils is considered in this paper. The effect which gas dissolved in the oil has on the dielectric strength of the oil is shown by experimental results of tests on the effect of temperature and pressure.
