Hi all, last week I made a couple of these Jacob's Ladders https://www.flickr.com/photos/97814409@N04/sets/72157647655795144/ The first was to be made into a true Jacob's Ladder, possibly inside a sealed glass/plastic enclosure filled with something other than air The second I wanted for a particular high voltage experiment It occurred to me last night that two secondaries could be put in series to make 60,000V (with the primaries driven in parallel) Logic would say that I can treat them as any other transformers but are there any HV considerations I should be aware of ?
