I had it explained once, that the insulation on the flyback windings, or
any other windings for that matter, are not necessarily perfect. The
insulation could be a bit thinner in one spot, or perhaps a tiny air
bubble in the insulation leaving a path to the conductor, etc. Maybe
even metal fatigue in the conductor itself. No man- made item is ever
perfect, so why would a wire be foolproof?
