C57.147-2008
IEEE Guide for Acceptance and Maintenance of Natural Ester Fluids in Transformers
The evaluation and handling procedures for natural ester transformer insulating fluids are covered. The transformer operator is assisted by the purpose of the guide, which is to evaluate the serviceability of new, unused fluids being received by the equipment manufacturer or service company and fluid in new equipment. The operator is also assisted by the guide in maintaining the fluids in serviceable condition.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
