Wow, very good links and nice desmontration! Thanks.
How did you determine that?In our case we had high levels of unwanted high frequency AC energy generated on the secondary side that melted the insulation and wrapping separating the shield from the secondary.
I could blame the engineer who wrote the specs but failing to see a hidden connection on a shield that almost never gets removed would be a little much as the yearly PM on this machine takes a 4 man crew almost a week to perform and re-qualify for production.So your failure could have been avoided had there not been a poor inspection regime.
This is definitely an engineering issue not a physics one, but well done for tracking it down.
Looking inside, seeing the burn patterns and making a educated guess the stuff is a good insulator but a poor RF dielectric that heats up rapidly.How did you determine that?
