To clarify this further, when Javatc is looking at this particular 
output, Javatc is looking at edge to edge proximity and not to the 
center of the conductors. For height inputs, center of conductor or 
center of top load is appropriate. But when it comes to a voltage 
ability to arc from point A to B as based on the voltage level and 
radius's of the conductors, then the nearest points are needed, and this 
means the edge of the conductor. In the same way that Javatc looks at 
arc voltage between 2 electrodes in the static gap, similar equations 
are used to determine the voltage at the inner turn, the radius's of the 
conductors, and the distance at which breakdown is probable. The value 
becomes a minimum proximity to prevent this.

Javatc does not simply look at horizontal distances. Imagine, the 
primary is 1" below the secondary and 1" larger? The actual proximity 
between the two coils is 1.279 inches (not 1"). If you raised the 
primary up to the bottom turn of the secondary, then it would be 1". So 
Javatc is looking at the "real" nearest edge to edge distance of the 
coils regardless of heights, widths, and even if both coils had angles 
(cone or inverse cones). In every possibility, the "nearest" edge of sec 
to pri is determined. And also, a recommendation is issued.

If ever the edge of one coil butted up against the other (crossed over, 
etc.), Javatc will give an error and prevent the program from running 
until the input is corrected. It is identified as a "crash". A crash 
can't occur physically and the program won't allow a crash condition to run.

Just so you know,
Bart
