Abstract

The electrical characteristics of two mineral oils of different viscosity, suitable for use in transformers and switchgears, are compared. It is found that, whereas the higher viscosity oil exhibits greater dielectric losses at more elevated temperatures, it has lower AC and impulse breakdown strength and is characterized by a lower partial discharge inception voltage.
