Hello All
I have a requirement to design an Isolation transformer(oil filled) with secondary being 15kV at 80kHz.
To isolate the transformer I have looked into teflon, glass and other isolating materials. When looking at material specification I noticed that manufacturers always give corona inseption voltages at 50/60Hz and nothing at 80kHz. I have tryd to get information form manufacturers but there was no luck there.
Does anyone out there knows the type and amount of insulatiuon I need(kV/micron) to have at 80kHz 15kV. Some graphs would be of great help.
Thank you all in advance
