Measuring Capacitance between Windings

There are expected values. Consider the capacitance may differ based on frequency per Capacitors. See: https://www.eevblog.com/forum/chat/custom-r-core-transformers-on-ebay/ This thread also links to a few places where you can buy custom made ones.

breakdown voltage of the windings. For 120V mains transformers it's around 1200V (maybe i think 1500V). See https://www.youtube.com/watch?v=NhWkxIBGkCM Lots of youtube videos on hi pot testing. /archive /2023_03.
