Scope

Certain electrical, dimensional, and mechanical characteristics are set forth as well as certain safety features of three-phase, 60 Hz., mineral-oil-immersed, self-cooled, pad-mounted, compartmental-type distribution transformers. These transformers are rated 5 MVA and smaller, with the high voltage limit of 34.5 kV system nominal voltage and below, and with low voltage limit of 15 kV system nomin...
