I intend to proof-of-concept today.
That snap is one reason why some shorts are easy to find while others are difficult. A short that arcs across an air gap can be identified from 100 feet away while you can be looking at a hard, metal-to-metal short and not recognize it.
The snap will also make diagnosis easier on sunny days.
these. Wire was crimped-into-place and then snipped flush with the end of the terminal to create the electrode that (we hope) will generate a spark. Obviously the gap size can be adjusted.
According to this academic paper, the break-down voltage for a 5mm air gap in clean, dry air will be approximately 4000V. 5mm is approximately the thickness of two nickels and one dime.
- The mounting needs to be figured out.
- The installation needs to be "ruggedized"
- The insulated portion of the blade needs to be extended
- The fence needs to be modified so runs are not doubly and triply connected. The diagnostic only works when there is a single feed into the run
