Decay Particles and Regeneration of Ester Dielectric Liquids A Challenge!

Ester dielectric fluids are no longer restricted to laboratory investigations and serve several transformers connected to the electric power network. Along with other technical aspects, it is also essential to understand the regeneration aspects of these alternative insulating liquids. Fuller’s earth is a popular and widely accepted adsorbent for regenerating mineral oils. The feasibility of using Fuller's earth for ester dielectric liquids is reported in this article.
