2. Classification and numerical data for liquid dielectrics
As the choice of a classification system for insulating liquids is arbitrary, we will use the one based on their origin
-
Category I: vegetable oils
They are essentially composed of triglycerides. Their composition is relatively simple (a few dozen molecules). They are produced from renewable resources (plants).
-
Category II: mineral oils
Derived from the refining of paraffinic, naphthenic or mixed petroleum crudes, they are also "natural" but non-renewable products. These oils are composed of several thousand different molecules. The content of potentially toxic aromatic compounds is minimized...
