Optical registration of the vacuum impregnation process of electrotechnical pressboard by transformer oil.

The paper presents a research stand developed to measure the kinetics of the vacuum impregnation process of electrotechnical pressboard with transformer oil. The object of the research was electrical pressboard made by Pucaro company impregnated by Nynas company Nytro Taurus oil. Studies were carried out in a vacuum chamber under reduced pressure. The results of the experiments allowed to determine the influence of reduced pressure on the impregnation process kinetics and to determine the diameter of the capillaries present in the electrotechnical pressboard.
