Interim report on guides for overloading transformers and voltage regulators

THE present war emergency has crystallized the need for additional information concerning the maximum load capability of modern-design transformers and voltage regulators in order that these apparatus may be utilized to a greater extent for meeting present and new load requirements with a minimum amount of new equipment, thus conserving critical war materials. It will be noted that the papers^1–3 presented at the AIEE convextion June 24, 1942 give somewhat divergent views on permissible overloads and on the effect of temperature on transformer insulation.
