Guide for Acceptance of Silicone Insulating Fluid and Its Maintenance in Transformers
|Publication Date:||2 February 1989|
(This Foreword is not a part of IEEE C57.111-1989, IEEE Guide for Acceptance of Silicone Insulating Fluid and Its Maintenance in Transformers.)
This guide was prepared by the Insulating Fluids Subcommittee of the Transformers Committee of the IEEE Power Engineering Society. The purpose of the guide is to identify standards for acceptance and maintenance of silicone fluid in transformers.
This guide recommends standard tests and evaluation procedures for silicone transformer fluid. Criteria for maintenance and methods of reconditioning of silicone fluid are described. It is not the intent of this guide to cover the subject of retrofilling transformers with silicone fluids.
The purpose of this guide is to assist the transformer operator in evaluating the silicone insulating fluids in transformers, fluid received from the manufacturer for filling transformers at the installation site, and fluid processed into such transformers. It also assists the operator in maintaining the properties of silicone fluid in operating transformers.
