This guide offers a methodology to determine, and thereby specify, the economic value of liquid immersed and dry-type distribution transformers, power transformers, and reactors. The guide provides formulas by which the costs of energy, power, financing, and the loading pattern of equipment can be converted to monetary values per kilowatt of the losses.

IEEE Guide for Loss Evaluation of Distribution and Power Transformers and Reactors
The economic loss evaluation of liquid-filled distribution and power transformers, dry-type distribution and power transformers, and reactors is covered in this guide.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
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No Inactive-Withdrawn Standards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
