C57.121-1988
IEEE Guide for Acceptance and Maintenance of Less Flammable Hydrocarbon Fluid in Transformers
IEEE C57.121-1988, IEEE Guide for Acceptance and Maintenance of Less Flammable Hydrocarbon Fluid in Transformers, covers the evaluation and handling procedures for less flammable hydrocarbon transformer insulating fluids. Its purpose is to assist the transformer operator in receiving new fluids, filling transformers, and 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No Inactive-Withdrawn Standards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
