Dielectric Strength Of Liquids: looking for data

Click For Summary
SUMMARY

The discussion focuses on the search for reliable data regarding the dielectric strength of liquid insulators with high permittivity and low viscosity. Specific liquids mentioned include ethylene glycol carbonate, propylene glycol carbonate, ethanol, methanol, and small ketones and aldehydes. Participants suggest utilizing the Handbook of Chemistry and Physics, specifically the 84th Edition, which contains relevant information in Section 6, pages 155 to 177. Additionally, they recommend using technical resources such as Scirus and IEEE Xplore for more in-depth research.

Hello all of you!

I'm looking for reliable data about the dielectric strength (=breakdown field) of liquid insulators with a high permittivity and a low viscosity and not too dangerous.

Examples of such liquids:
- Ethylene glycol carbonate. Propylene glycol carbonate. Maybe the oxalates and sulphates.
- Ethanol. Methanol.
- Small ketones and aldehydes
- Small phosphates?
- Furfuraldehyde maybe.

I couldn't find them in my Handbook of Chemistry and Physics (1990), in Wikipedia, nor on the Web.

The use would be in an electrostatic alternator which looks very interesting (MW or GW range!), as I describe it there:

I suggest beginning to read on page 2 with the sketches and diagrams.

Thank you!

Learn to use the index of the handbook! Look under "Dielectric Constant - Liquids" . In the 84th Edition it is in Section 6 pages 155 to 177.
 
I already have all permittivities.

Where do you find the dielectric strength?
 
Thank you!
