This paper gives information on the electrical and physiochemical characteristics of six
different types of palm oil compared with traditional mineral oil. We found that natural …

The paper presents the results of comparative studies of thermal properties of various types
of natural esters used as electroinsulating liquids in transformers. Adequate thermal …

This study uses natural fibre, which is moisture absorbent, as an innovative and economical
filler for insulating oil. Rice husk (RH) is a natural fibre known to have water-absorbing …

The transformer oil and impregnated paper are widely used as electrical insulation design of
power transformers. The dielectric strength of the oil paper insulation in transformers may …

Vegetable-oil-based insulating fluids have attracted significant attention in the field of
electrical insulation, and are implementing the application of mineral oil, which has been …

This study reports on the AC breakdown properties of soybean oil after the ester exchange
reaction. We observed the effect of the amount of NaOH (4.0 to 10.75 [g]) and ethanol (250 …

Replacement with natural esters (retrofilling) is an alternative solution to extend the life
expectancy of an oil-filled transformer containing mineral oil. During the retro-filling process …
