The procedures cover: (1) the calibration and use of field instruments for detecting and estimating the amount of combustible gases present in gas blankets above oil, or in gas detector relays; (2) the use of fixed instruments for detecting and determining the quantity of combustible gases present in gas-blanketed equipment; (3) obtaining samples of gas and oil from the transformer for laboratory analysis; (4) laboratory methods for analyzing the gas blanket and the gases extracted from the oil; and (5) interpreting the results in terms of transformer serviceability. The intent is to provide the operator with positive and useful information concerning the serviceability of the equipment. An extensive bibliography on gas evolution, detection, and interpretation is included.<br />\n \t\t\t\t<br />\n This guide applies to mineral-oil-immersed transformers and addresses:<br />\n 1) The theory of combustible gas generation in a transformer;<br />\n 2) The interpretation of gas analysis;<br />\n 3) Suggested operating procedures;<br />\n 4) Various diagnostic techniques, such as key gases, Dornenberg ratios, and Rogers ratios;<br />\n 5) Instruments for detecting and determining the amount of combustible gases present;<br />\n 6) A bibliography of related literature """ #metaKeywords: null #metaDescription: null #shortDescription: "IEEE Guide for the Interpretation of Gases Generated in Oil-Immersed Transformers" -notes: "Inactive-Withdrawn" } ] #currentLocale: "en_US" #currentTranslation: null #fallbackLocale: "en_US" #variantSelectionMethod: "match" #productTaxons: Doctrine\ORM\PersistentCollection {#130338 …} #channels: Doctrine\ORM\PersistentCollection {#130331 …} #mainTaxon: Proxies\__CG__\App\Entity\Taxonomy\Taxon {#7517 …} #reviews: Doctrine\ORM\PersistentCollection {#130335 …} #averageRating: 0.0 #images: Doctrine\ORM\PersistentCollection {#130333 …} -supplier: Proxies\__CG__\App\Entity\Supplier\Supplier {#7683 …} -subscriptionCollections: Doctrine\ORM\PersistentCollection {#130304 …} -apiLastModifiedAt: DateTime @1754517600 {#130305 : 2025-08-07 00:00:00.0 Europe/Paris (+02:00) } -lastUpdatedAt: DateTime @1578006000 {#130347 : 2020-01-03 00:00:00.0 Europe/Paris (+01:00) } -author: "" -publishedAt: DateTime @711756000 {#130354 : 1992-07-22 00:00:00.0 Europe/Paris (+02:00) } -releasedAt: null -confirmedAt: null -canceledAt: DateTime @1139180400 {#130312 : 2006-02-06 00:00:00.0 Europe/Paris (+01:00) } -edition: null -coreDocument: "C57.104" -bookCollection: "" -pageCount: 37 -documents: Doctrine\ORM\PersistentCollection {#130344 …} -favorites: Doctrine\ORM\PersistentCollection {#130342 …} } +label: "Historical" +icon: "historical" -mostRecentAttributeCode: "most_recent" -localeContext: Sylius\Component\Locale\Context\CompositeLocaleContext {#1833 …} } |
