Ester Fluids for Power Transformers at >100kV

Mark Lashbrook ; Midel

Sažetak

Typically for high voltage power transformers mineral oil is used for both cooling and electrical insulation. However mineral oil has some shortcomings in terms of fre safety and environmental impact. The answer to these concerns is to use a more fre safe and environmentally friendly alternative liquid, such as an ester. In order to do this at higher voltages, designers need to understand any differences in thermal and electrical properties. This article aims to give a brief overview of the relevant properties of ester liquids and how this can affect transformer design.
