Identification of Critical Values Based on Natural Ester Oils as Potential Insulating Liquid for High Voltage Power Transformers

Nihat Pamuk [1]


This study tries to bring a complex summary of properties of natural ester fluids from the point of view of electrical insulation fluid for high voltage power transformers. Although many papers have been published in this area, this study try to address some less known problems which however plays a key role in new fluid practical applications. Some differences compared to mineral oils are discussed in study. The critical values that might occur in the future for industrial applications are proposed, evaluated and discussed.

Natural esters, insulating liquid, power transformer, mineral oils
