Hi Marco,

	For my coils, I used E-Tesla5 to plot the E-fields around my coil.  I then
looked at these fields and the stresses involved to try and determine a
"smooth and happy" field pattern around the coil and the terminal.  I know
there is a lot of guess work and armwaving with this but looking at the
fields does give one an idea if the terminal so too high or not.  E-Tesla5
can also model a corona ring and such...

Cheers,

	Terry
