Due to the growing interest in environmental concerns, synthetic and natural esters have
become the key focus of the picture in the last two decades as insulating fluids for high …

Green insulating fluids are playing a vital role in insulation design of the distribution
transformers. Traditionally used mineral oil has lesser biodegradable and low fire resistant …

The energy demand of the whole world is dominated by petroleum products for centuries in
the field of critical application like electricity. The application of mineral oil in power system …

Transformers are the vital units of power system and the major dielectric used in transformer
is petroleum based mineral oil, which acts both as an insulating medium and potential …

Transformer liquid dielectrics evolved where mineral oil has been the dominant choice until
emergence of synthetic esters and natural esters. Natural ester-based oils have been under …

Conventionally, mineral oil impregnated with solid insulating materials has been used as an
insulating medium in the transformers. On the other hand, mineral oil is less biodegradable …

This work is focused towards identifying alternate insulating medium for replacing the
mineral oil. With this aim, investigations are carried out with natural esters based vegetable …

For power transformer applications, this study explores an alternative insulating liquid. With
this aim, edible natural esters such as refined Olea europaea (olive oil), rice bran oil, soya …

Transformer mineral oil which is normally hydrocarbon based is non-biodegradable and
pollutes the environment in all aspects. Though vegetable oils are eco-friendly in nature and …

This paper presents the results of testing the electrical and fire properties of mineral oil and
low-viscosity natural ester mixtures. Properties such as breakdown voltage, relative …
