Power transformers are essential elements in electrical systems and the end of their useful
life is frequently conditioned by the state of the cellulosic insulation materials inside them …

The oil-paper insulation system is a critical component that serves excellent insulation
properties in a power transformer. It has high dielectric strength that can withstand high …

Sustainable materials, such as vegetable oils, have become an effective alternative for liquid
dielectrics in power transformers. However, currently available vegetable oils for transformer …

In this work, thermal aging aspects of mineral oil, ester oils (synthetic and natural), mixed oil
have been reported. All the samples were thermally stressed at 110° C, 140° C, 160° C, and …

Mineral oil is widely used as liquid insulation in high voltage equipment. Due to
environmental considerations, recently natural esters have been considered as naturally …

Natural esters have become of interest for the industry in recent years as dielectric liquids for
power transformers, and many studies are focused on their dielectric and chemical …

Study of alternate fluids for transformer and their combination with traditional ones is an
interesting area of research. The intent of this work is to investigate the thermal ageing …

Operational factors are known to affect the health of an in-service power transformer and to
reduce the capabilities and readiness for energy transmission and distribution. Hence, it is …

Numerous experimental investigations were carried out by several researchers exploring
vegetable oils as substitutes for transformer oil since these vegetable oils are …

Introduction/purpose: Several studies in the area of the development of nanofluids for power
equipment have left a gap unfilled as to how to determine the best oil among the produced …
