Safely testing 22 kV capacitors
Ignoramus27088 wrote...
Got myself some capacitors for $10 apiece. http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7603382621 The specs are 22 kV, 1 uF, discharge capacitor. See http://igor.chudov.com/tmp/cap.jpg The seller was wrong in describing them as 22 VOLT capacitors. They are 22 KILO volt capacitors. (the seller is Fermilab). They are similar to this one: http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7598631638 but have twice more capacitance. Anyway, here is my question. I have a 9 kV DC power supply. (a Franceformer). How can I safely test these caps before selling them. At 22 kV, they can store about as much energy as a .22 bullet, according to my calculations. It would be less at 9 kV, but still, obviously, very deadly. So. What is a safe way to charge them, verify that they hold the charge, and then DIScharge them at 9 kV. Ignoramus, I strongly protest your post. Here is an interesting conversation that you started, with 32 posts so far, according to the Google usenet archive, of which you have made 14, or 44% of the posts. Yet you marked all your posts "do not archive" - which means they will be removed from Google Groups in 6 days, thereby severely damaging the stored thread. With this kind of callous action on your part, one wonders why others should even take part in the already-broken, soon-to-be-bogus conversation. What the h____ are you doing here? -- Thanks, - Win |

Gave us: Ignoramus, I strongly protest your post. Are you a mexican illegal immigrant, protestor too? Here is an interesting conversation that you started, with 32 posts so far, according to the Google usenet archive, of which you have made 14, or 44% of the posts. Yet you marked all your posts "do not archive" - which means they will be removed from Google Groups in 6 days, thereby severely damaging the stored thread. I can't believe that you wasted so much of your time doing a statistical analysis on a technical thread which you haven't even posted any contributory response to. You are the antipathy of what it is to be "smart". With this kind of callous action on your part, one wonders why others should even take part in the already-broken, soon-to-be-bogus conversation. What the h____ are you doing here? You're an idiot. Enough of ALL of the responses provided are archived, and would actually make reading the question for a given response easier than scrolling back up through the thread chain. What the **** are you doing mouthing off? You COULD actually try posting on topic, contributory material. |

Demanding that he do it differently is no different than the people who ask a question and demand an email response. (equally stupid and arrogant, is the point I'm making). |

Maybe Ignoramus is within his rights. But Win has a very good point. In any event, if Ignoramus alienates Win and just a few other knowledgeable regulars here, his (Ignoramus's) experience will be badly degraded. So he may want to think seriously about Win's protest. --Mac |

Then the archives would be nearly useless. All that would remain would be newbies asking incomplete questions, flames, and idiotic remarks. There was a time when they archived regardless of the flag setting. With all the money google has, one would think that they would have several hundreds of terabytes of archival data online and available. One would think they would have other service providers using their servers as the master archive. That is still no excuse for a poorly planned web interface to Usenet. |
