Electric breakdown strength measurement in liquid dielectrics

2010 9th International Conference on Environment and Electrical Engineering, 2010
Development of new technologies and materials in electric power engineering is very closely associated with question of ecology presently. Daily, there is consumed thousands tons of electro-insulating materials, including of electroi-nsulating oil, which are the main component of paper - oil transformers by the electric power systems devices production.

High energy storage density of tetragonal PBLZST antiferroelectric ceramics with enhanced dielectric breakdown strength

, 2020
Tetragonal PBLZST antiferroelectric ceramics is the most studied energy storage material because of its unique double hysteresis loops. However, the dielectric breakdown strength of PBLZST is relatively low, which severely restricts to acquire high ...

Effect of pores on dielectric breakdown strength of alumina ceramics via surface and volume effects

, 2020
To investigate the effect of pores on the dielectric breakdown (DB) of alumina ceramics under AC voltage, we implant pores at different positions (surface, interior, and the whole body) of the ceramic samples by adding the polyvinyl alcohol solid ...

The breakdown strength of two-layer dielectrics

11th International Symposium on High-Voltage Engineering (ISH 99), 1999
In paper the experimental results of the breakdown strength study for the two-layer dielectrics under the high electric field are given. The relation between the breakdown strength (E b ) and the boundary position (ξ) between layers for the two-layer dielectrics is anomalous in character.

On the role of electron attachment in the breakdown strength of gaseous dielectrics

Journal of Physics D: Applied Physics, 1981
Experimental data on electron attachment and breakdown voltages Vs for two groups of strongly electron attaching gases-perfluorocarbons and freons-and some of their mixtures with electron slowing-down gases have been used in an effort to quantify the role of electron attachment on the breakdown strength of gases.
