Hi guys!
Anyone knows the term "across the isolating distance" mean?
This concept is shown in the catalog ABB NALF and IEC 62271.
Thank you for your help!

Hi LiteYear, thank for you reply...
Now, the Pashen´s curve exposes what im saying (distance need increasing over 1000 masl), but i understand for BIL which is the basic insulation level for one material, for example:
For epoxy dry tranformer, IEC 60076-11 indicate for transformer for use at...
Hi all:
Im new in foro and i have some query about BIL.
Why BIL are derrating in high altitude (over 1000 masl)?
I have the impression that the distances are increasing at a higher altitude and not "material quality" (eg porcelain insulator).
I hope we can discuss and present different...
