Investigating R&D Committee on electrical insulation of dielectric liquids and applications of EHD, ER.MR
Keyword : Environment-friendly insulating oil, Breakdown phenomena, Diagnostic techniques of degradation, EHD phenomena ER.MR fluids
It is expected increasingly that several liquids including insulating oils are put to practical use as an effective material for a field of technologies on the insulation of power apparatuses and application of liquids. In this investigative committee, a tendency of the present and future on the development of environment-friendly insulating oils and physicochemical properties of oils, pre-breakdown and breakdown phenomena in insulating oils, the dynamic behaviors of EHD phenomena in liquids and EREMR fluids and their applications were mainly investigated and discussed. @This investigation report describes the results obtained on the following main items: (1) the development of environment-friendly insulating oils and novel power apparatus, (2) the insulation performance of insulating oils based on the pre-breakdown and breakdown phenomena, (3) EHD mechanism in liquids and applications of EHD phenomena, (4) the development of EREMR fluids and techniques on their applications, (5) the diagnostic techniques on degradation of practical oils.
By these investigations, this report was completed with the contents including environment-friendly insulating oils as a substitute of mineral oil, insulation performance of insulating oils, techniques on applications of EHD phenomena and EREMR fluids, the diagnostic techniques on degradation of practical oils, etc.
