Mineral oils are extracted from crude petroleum by refining and fractional distillation processes. These oils are complex composition of several hundreds of allied aromatics involving hydrogen and carbon molecules. Mineral insulating oil consists either saturated paraffin and naphthenes or unsaturated aromatics in appropriate compositions depending upon the requirements of manufacturers to satisfy clients and applications [19]. Mineral oil may be paraffinic base or naphthenic base depending on the ratio of their proportion exceeding one over the other. Suitable number of aromatics is also added to these oils for developing appropriate dielectric parameters.
