IEEE Guide for the Reclamation of Insulating Oil and Criteria for Its Use

Detailed procedures are provided for reclaiming used mineral insulating oils (transformer oils) by chemical and mechanical means to make them suitable for reuse as insulating fluids. Reclamation procedures are described, as are the test methods used to evaluate the progress and end point of the reclamation process and the essential properties required for reuse in each class of equipment. Suitable criteria for the use of reclaimed oils are identified. The use of oil in new apparatus under warranty is not covered.

Guide for Reclamation and Reconditioning of Insulating Liquids

This guide applies to mineral oil, natural esters, synthetic esters, silicone and less flammable hydrocarbon (LFH) insulating liquids used in electrical equipment. The guide covers definition and description of reclaiming and reconditioning procedures; the test methods used to evaluate the progress and end point of the process. This guide does not cover the use of insulating liquids in new apparatus under warranty and re-refining of insulating liquids.
