Abstract

Cigre working group A2.56 Power Transformer Efficiency conducted a survey among utilities worldwide to determine how maximum allowed losses are managed in their existing specifications of transformers—whether the losses are capitalized and how the load and no load, loss factors are calculated etc. Findings of that survey will be presented in the paper.
