Abstract

In this paper, the recent trends of electrical insulation in liquid dielectrics am described. The development results of the higher stress/compact design equipment, environment-friendly ester-oil, insulation diagnostic technique, higher temperature application, etc., as well as cryogenic electrical insulation are introduced. In particular, it is pointed out that the charge carriers in liquid dielectrics will be a key factor to control the higher stress electrical insulation and therefore the basic research on charge behavior and the physical mechanism should be extended for the future.
