Transformer, terminal connected to its own core?

    Hello,
    For fun, I opened my microwave.
    Looking at the transformer, I noticed that one terminal of the
    secondary winding is connected to its own transformer core.
    From my understanding of transformer theory, I do not understand that.

    That would most probably be the HV return...

    They probably want to make _really sure_ that if there's a fault in the
    secondary winding it blows a fuse instead of electrocuting an 11-year old.
     
  4. Yes. Earth ground IS the HV return. One good reason to use a properly
    grounded outlet.
