Insulating vegetable oils are fire-resistant and environment-friendly liquid dielectrics. This paper presents a type of nano-modified insulating vegetable oil. The nano-modified insulating vegetable oil was prepared by homogeneous precipitation deposition of ferroferric oxide nano-particles. It was characterized by a laser nano-particle size analyzer. Its electric properties, including AC breakdown...
This paper presents the basic physical, chemical and electrical properties of a type of rapeseed oil based dielectric liquid. Dielectric properties including relative dielectric permittivity, dissipation factor, and breakdown voltage of the rapeseed oil paper insulation are presented and also compared with those parameters of mineral transformer oil paper insulation. Moreover, four types of small...
