Investigations on biodegradable liquid insulating medium for electric power apparatus applications

Abstract

Mineral oils are being used as a liquid insulating medium in high voltage power apparatus applications for a long period However the search for alternate insulating oil comes in mind of researchers because the mineral oil is nonbiodegradable toxic in nature and petroleum products are eventually going to run out Mineral oil application in the power system apparatus can be potentially risky to the environment especially when there are equipment failures or spill of oil to the soil or water stream In recent times many research works are being carried out to replace mineral oil with suitable vegetable oil Before considering vegetable oils for liquid insulation applications it is essential to investigate the electrical physical and chemical characteristics of vegetable oils newline
