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 …

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 …

The reliability of power transmission and distribution depends up on the consistency of
insulation in the high voltage power transformer. In recent times, considering the drawbacks …

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 …

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 …

The urge for a sustainable and non-polluting industry has raised the need for a search for an
alternative insulating fluid that could be used in transformers, because of the negative …

This paper presents a study of lightning impulse breakdown voltage of palm oil under
needle/plane and needle/sphere electrode configurations. All tests were carried out at gap …

In recent times, development of nanofluid insulation for power transformers is a hot research
topic. Many researchers reported the enhancement in dielectric characteristics of nano …

Understanding the impulse discharge behaviour of natural ester (NE) is crucial for its safe
application in high‐voltage transformers. The ionisation potential (IP) of triglycerides plays a …
