Insulating Materials at Very Low Temperatures: A Short Review

Abstract

In this paper, a short review is given on insulating materials at very low temperatures. Various insulating materials are investigated in terms of phenomena such as partial discharges. Some of the factors affecting the behavior of the insulating materials at very low temperatures, such as the quality of electrode surface, the stressed insulation volume and the existing bubbles, are also reported and commented upon. Proposals for future research are also discussed.

Alternative Fluids – with a Particular Emphasis on Vegetable Oils – as Replacements of Transformer Oil: A Concise Review

“…Other approaches for alternative liquids, such as electronegative fluids or liquefied elemental gases will not be mentioned here, since the former played more the role of refrigerants, and the latter were destined for use in superconducting magnets in high energy particle machines [8]. Moreover, the subject of liquefied gases was partially dealt with in a recent review publication [30].…”
