I got my hands on an old 3kVA step-down control transformer that I can adapt into a beauty of a 1:1 isolation transformer. But I'm wondering how worried I shouold be about insulation breakdown on my floating secondary?
Is there any way to stabilize the secondary voltage relative to ground? I was thinking that something as simple as grounding the transformer case might provide a secondary voltage reference via capacitive coupling. Yes/No?
I don't have any information on the BIL, all I know is the maximum primary voltage is 504V.
Anyone have any answers? Thanks.
