Development of Promising Insulating Oil and Applied Techniques of EHD, ER·MR

Abstract

The development of an environment-friendly insulating liquid has been noticed for a new design of oil-filled power apparatus such as transformer from viewpoints of the protection of the environment. The dielectric liquids can also widely be applied to various fields which are concerned in the electromagnetic field. This article introduces the recent trend on promising new vegetable based oil as an electrical insulation, and EHD pumping, ER fluid and MR fluid as the applied techniques of dielectric liquids.
