Alternative transformer oil has been investigated universally in the past years. Different types
of vegetable oil have been proposed and evaluated as replacements for conventional …

This review is conducted following a systematic approach by adopting the Preferred
Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline and using …

Natural esters have high viscosity in their triglyceride form. Transesterification reduces their
viscosity but lowers their flash point. In this paper, we proposed an optimal blend of natural …

Vegetable oils are considered nowadays as a potential alternative to Mineral Oil (MO) for
dielectric insulation fluids in transformers due to its high biodegradability, non-toxicity and …

Increasing awareness of safety and the environment demands the replacement of mineral
oil by bio-oils in many electrical applications. Palm oil has been identified as a potential …

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 …

This paper presents a sealed ageing study of palm oil (PO) and coconut oil (CO) in the
presence of insulation paper. The type of PO under study is refined, bleached, and …

With the increasing requirements for environmental protection, the development of
vegetable insulating oil is deeply valued by the power industry. Palm oil is considered as a …

Mineral-based oil is now often used for transformer oil. Unfortunately, this kind of oil is
harmful and unfriendly to the environment, necessitating the use of vegetable-based …

Use of traditional mineral oil (MO) as a liquid insulation in transformers has spanned more
than 130 years. However, MO has poor heat resistance, a low ignition point, and is a non …
