I an constructing a large insect zapper (wasp/hornet) as the store bought ones are not up to the task. Originally used a 12kv neon transf. and it effectively cooked the critter but had a runaway arc issue once the arc was initiated. While pretty, it wasn't the appropriate solution. The current attempt is using a MOT. Approximately 2200v but higher current.
Most MOTs have one end of the hv coil inaccessibly bonded to the frame. Both ends are accessible on this one. As I plan to use the microwave diodes and a pair of microwave caps to turn this into a dc source approx 4500 to 5kv I will need both ends of the coil not grounded.
The question: leave the one end bonded to the frame and insulate the HEAVY MOT from the case, or hook both ends of the hv coil (NOT bonded to the frame) then mount (ground) the MOT frame with the case?
Also shunts in or out?
The objective here is a lightning bolt that self extinguishes. I realize shunts out will increase current in/out of the MOT and I do have room to put a second MOT shorted as an inductor for limiting. Thoughts or suggestions?
Anything I am overlooking?
The objective here is to NOT maintain an arc but simply a killing arc then, next critter. I do have additional caps if the suggestion is a cap bank.
