1. [AMPS] Vacuum Variable voltage rateing (score: 1): Author: Wlfuqu00@pop.uky.edu (William Fuqua); Date: Thu, 12 Apr 2001 11:26:07 -0400; Looking at Jenning's data on Vacuum Variable capacitors I noticed that the voltage rating on the capacitor is the Test Voltage and the working voltage is less. For example a 3000volt cap Cxxx-300-3 h; /archives//html/Amps/2001-04/msg00267.html (7,931 bytes)
2. [AMPS] Vacuum Variable voltage rateing (score: 1): Author: philk5pc@tyler.net (Phil Clements); Date: Thu, 12 Apr 2001 10:51:32 -0500; All I use the 3000 volt caps for are loading. The tuning cap should be rated for at least 7.5 kv if you are going to run 6 kv Ep on a 4 X1, IMO. You can get away with pushing limits on vacuum variabl; /archives//html/Amps/2001-04/msg00270.html (9,067 bytes)
3. [AMPS] Vacuum Variable voltage rateing (score: 1): Author: 2@vc.net (measures); Date: Thu, 12 Apr 2001 08:53:07 -0700; ? DC is normally used to test vacuum caps. Withstanding (breakdown) potential decreases as freq. increases. At 30MHz, a 60% derating is commonly used. - Rich..., 805.386.3734, www.vcnet.com/measures; /archives//html/Amps/2001-04/msg00271.html (8,235 bytes)

[AMPS] Vacuum Variable voltage rateing (score: 1): Author: dcoolica@planet.eon.net (Denis Coolican); Date: Thu, 12 Apr 2001 21:00:36 -0500; I ran into problems with an air variable that I had increased the plate seperation to handle more power at that higher Z on a 4-1000A.. I calculated that the max RF peak voltage would be 4.5KV. When; /archives//html/Amps/2001-04/msg00291.html (9,072 bytes)
