Properties of Vegetable Fluids: A Green Insulator for Power Sector

  • Dhorali Gnanasekaran
  • Venkata Prasad Chavidi
Part of the Materials Forming, Machining and Tribology book series (MFMT)


This chapter deals with the properties (physical, thermal, chemical, and electrical) of natural esters to be used as insulating fluids. This chapter also describes the effect of various additives (antioxidant additive, pour point depressant, etc.) on the properties of vegetable oil-based natural esters. It also gives detailed discussion on current research scenario of vegetable oil-based ester fluids for power sector. It also includes challenges and technical difficulties of vegetable ester fluids as a liquid insulator; it also covers comparison between vegetable oil fluids and mineral oils as liquid insulators for transformer application.
