This International Standard describes how the concentrations of dissolved gases or free
gases may be interpreted to diagnose the condition of oil-filled electrical equipment in service
and suggest future action.
This standard is applicable to electrical equipment filled with mineral insulating oil and
insulated with cellulosic paper or pressboard-based solid insulation. Information about
specific types of equipment such as transformers (power, instrument, industrial, railways,
distribution), reactors, bushings, switchgear and oil-filled cables is given only as an indication
in the application notes (see Annex A).
This standard may be applied, but only with caution, to other liquid-solid insulating systems.
In any case, the indications obtained should be viewed only as guidance and any resulting
action should be undertaken only with proper engineering judgment.dition 3.0 2015-09 INTERNATIONAL STANDARD NORME INTERNATIONALE Mineral oil-filled electrical equipment in service – Guidance on the interpretation of dissolved and free gases analysis Matériels électriques remplis d'huile minérale en service – Lignes directrices pour l'interprétation de l'analyse des gaz dissous et des gaz libres IEC 60599:2015-09(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 標(biāo)準(zhǔn)截圖
