The mineral oil or synthetic oil in conjunction with paper is mainly being applied as dielectric
medium in many of the high voltage apparatus. However, the advent of high voltage levels …

Heat transfer fluids are a crucial parameter that affects the size and costs of heat
exchangers. However, the available coolants like water and oils have low thermal …

Recently, the study of transformer oil-based nanofluids became of great interest, due to their
prospective properties as a dielectric and cooling medium. However, agglomeration of …

Given the adoption of ultrahigh-voltage ac and dc power transmission, it is desirable to
develop a new kind of oil-paper insulation system, with higher dielectric strength and smaller …

In November 2017, the first±1100 kV high-voltage direct-current power transformer in the
world, which was made by Siemens in Nurnberg, passed its type test. Meanwhile, in early …

Nanofluids, formed by adding nanoscale particles to insulating oil, are stable and
homogeneous suspensions that present advanced performance of electrical insulation and …

Polyhedral oligomeric silsesquioxane (POSS) has eight substituent groups, which can be
substituted with various substances to obtain different modification effects. In order to study …

In this paper, frequency dependent dielectric parameters of pure oils and nanofluids have
been studied at different temperatures to investigate any improvement of the dielectric …
