Re: [TCML] Design questions



Hi Dennis,

If you put a tape measure in a straight line between the two nearest edges of the coils, this is the distance you'll measure.
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
