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.<\/p>\n

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<\/span>).<\/p>\n

This standard may be applied, but only with caution, to other liquid-solid insulating systems.<\/p>\n

In any case, the indications obtained should be viewed only as guidance and any resulting action should be undertaken only with proper engineering judgment.<\/p>\n
