IEC 60814 Insulating Fluids - Determination of Water by Automatic Coulometric Karl Fischer Titration of Oil Impregnated Paper and Pressboard

EUROLAB laboratory provides testing and compliance services within the scope of IEC 60814 standard. Explains the methods for the determination of water in isolation fluids and in oil-impregnated cellulosic isolation with a coulmetrically formed Karl Fischer reagent.

For liquids in use, the accuracy of the method may be affected by the presence of contaminants. The method has been designed to be particularly suitable for hydrocarbon and ester liquids. with the other liquids, especially silicone liquids, reagents that do not contain methanol should be used.

Iodine produced by electrolysis reacts similarly with water. The endpoint of the reaction leading to Karl Fischer reactions is determined by a couple.

At the end of the titration, the excess iodine depolarizes the double platinum electrodes, giving a change in the current/voltage ratio. Used to activate the endpoint indicator and stop the current integrator.
