19、ation of Liquid-Immersed Power Transformers.) Power transformers usually represent one of the most important and most costly single items in substations. Furthermore, particularly for large transformers, their failure usually results in lengthy outages or downgrading of service. For these reasons, a
20、 high degree of care is required to properly install and maintain them. Because of these considerations, IEEE and other standards-developing organizations have published, since at least the early 1920s, various recommendations for testing, installing, and maintaining transformers. This guide consoli
21、dates and replaces IEEE Std C57.12.11-1980 and IEEE Std C57.12.12-1980, which cover large transformers, and ASA C57.93-1958, which covers smaller units. The intention of this guide is to assist users and manufacturers in the shipping, handling, inspection, installation, and maintenance liquid-immers
22、ed power transformers and to assure that the units are placed in service in acceptable condition to provide years of reliable service. This guide also provides information on developing a maintenance and monitoring program. This guide discusses two sizes of transformers: Clause 3:501 kVA to 10 MVA (
23、oil/air cooled OA) with primary windings less than 69 kV Clause 4:10 MVA and above with high-voltage windings 69 kV and above The working group of this guide recognizes that substantial variations exist among transformer manufacturers on certain aspects of transformer installation requirements and t
24、hat these vary with size and voltage. This guide attempts to accommodate these variations and facilitate a full understanding between manufacturer and user. Generally, the user must conform to the manufacturers minimum recommendations in order to obtain a proper warranty. The Accredited Standards Co
25、mmittee on Transformers, Regulators, and Reactors, C57, that reviewed and approved this document, had the following membership at the time of approval: P. E.
