New, large, oil-immersed power transformers with high-voltage windings rated 69--287 kV inclusive are primarily considered. Inspection on receipt, internal inspection, handling, assembly of fittings, vacuum treatment, filling with oil, tests,…
Large, oil-immersed power transformers with high-voltage windings rated 345 kV and above are considered. Inspection on receipt, internal inspection at the site, preliminary oil filling, assembly, vacuum treatment and final…
This standard prescribes insulation levels and dielectric test requirements for power transformers where: (1) The transformer insulation levels and dielectric test requirements are explicitly specified to be in accordance with…
Superseded by IEEE Std C57.12.20-2005. This standard covers certain electrical, dimensional, and mechanical characteristics and takes into consideration certain safety features of single- and three-phase, 60-Hz, mineral-oil-immersed, self-cooled, overhead-type distribution…
This standard is intended for use as a basis for determining performance, interchangeability, and safety of the equipment covered, and to assist in the proper selection of such equipment. This…
Electrical, dimensional, and mechanical characteristics and certain safety features of single-phase, 60 Hz, mineral-oil-immersed, self-cooled, distribution transformers with separable insulated high-voltage connectors are covered. Ratings, testing, and construction are discussed.…
