Well I removed the air gap and my results didnt get any lower so I'm thinking that the air gap doesn't really do anything...

Ok, I think I get what you are saying. So long as the air gap is not large enough to have a higher breakdown voltage then the Dielectric, the air gap doesn't matter?

Well I can do that and I have been doing that. I just want to see if I can verify my results with Math since I am being told that the numbers I am getting seem to be a bit high. We are trying to test our parts dielectric strength and we need to have an air gap so we can use less tooling so...

And I can't seem to find my source of the information I got. I thought I had saved the article but I guess I didn't

hmm... well I am trying to find what voltage it should take to break through multiple materials so I am unsure what the final voltage should be. from my initial testing i am getting 33-38 kV. I am just trying to find a way to calculate it to verify my results.

I got the 30 and 4 from the dielectric strength of the materials. The dielectric strength of the dielectric layer is 30 kV/mm and it is going through 1 mm and the air gap is 4 mm and the dielectric strength of air is about 1 kV

Its really just adding the 2 voltages together?

Ok well the first branch has a voltage of 30 kV and the second branch has a voltage of 4 kV.

hmm... How about knowing the max voltage that will be across both parallel branches seperatly? Would that give me enough knowledge to then find the source voltage? This isn't exactly a circuit equation. I am actually trying to find breakdown voltages across multiple layers of materials...

1) I want to find out the source voltage. 2) I don't know, maybe... 3) No, I am trying to figure this out for my job. I am an Mechanical Engineer that is trying to figure out EE stuff and I am a bit lost. ha

I have a circuit I need to find a voltage on. Is there a way to figure it out on the provided picture in here? Thanks

Alright well I found some data on the glass I am using. It's not real helpful since in the few spots I found info the dielectric strength ranges from 16-30 kV/mm. The gap between the electrode and the glass is very small (almost touching) and the gap from the edge of the glass is about 3.5mm...

So if I go by the glass number there it should break through at about 12 kV. I didn't get a result till 33-38 kV.

Also, any idea how compareable the window glass in that link is to Simex glass tubing?

Well I have already been doing some testing but I was trying to find calculations to verify my results.
