Losses in Transformers for Use With Mercury Arc Rectifiers

This paper developes the mathematical formulas and discusses the assumption involved in the methods for determining the losses of transformers for use with mercury arc rectifiers. The methods discussed have been proposed for the A. I. E. E. Standards. From test readings of current taken under service conditions, a rigid calculation of copper losses is made. From this calcutlation it is shown that the proposed methods give values that are accurate within satisfactory limits. The paper also presents the advantages of the proposed methods for determining the losses of transformers for use with mercury arc rectifiers.
