Tank capacitor burn in
cc: tesla-at-grendel.objinc-dot-com
Richard,
Last night I was burning in my recently completed .02mfd rolled tank
capacitors as suggested in the Keelynet capacitor file. I used a 12kv, 60ma
neon transformer and conected each transformer output to one capacitor,
connected the other two capacitor terminals together and connected this point
to the transformer center tap (case). I ran the transformer on a variac at
about 50%. Each capacitor should have had about 3kv across it. The
transformer got extremely hot. I had a large fan blowing on it after about 2
hours. I ran it for 4 hours total. The transformer was so hot you could not
hold your hand on it. A small amount of oil (melted tar I bet) actually
seeped out of the bottom of the transformer. I thought the neons were
current self limiting and they would not burn up under load. Am I missing
something? Is there a better way to do this?
Thanks, Ed Sonderman
