Abstract
The article presents the effect of pressure on the bubble effect in moist paper-oil insulation. In order to investigate the influence of pressure on the bubble effect, a measurement stand was made and experiments were carried out on electrotechnical pressboard with a humidity of 3.5%. It was observed that water boiling in pressboard is already present at a pressure of about 500 hPa for a temperature of 21°C which, taking into account the properties of nanoparticles may be evidence of the presence in pressboard nanodrops of water.Keywords
